Warnings and Known Bugs
-----------------------
- If you are using a Videum (Winnov) video-capture card and
have the new 2.0 drivers, you can change the audio input for
the card by opening the Videum Configure program (under the
Winnov Videum program group) and selecting the desired audio
input for the video input being used with NetMeeting. The default
is to use the Camera microphone for the MXC video connection
and Line Input for all other video connections. After you do
this, the correct audio input will be selected when you start
NetMeeting.
- Audio input for users of Winnov cameras will automatically be
switched whenever video is in use. If your video is connected
using the MXC connection, the camera input will be used for
audio. If your video is connected using the Composite or
S-Video connection, the Line Input will be used for audio.
You can solve this problem by upgrading to the new 2.0 drivers
and by using the Videum Configuration application.
- Users of NetMeeting and Intel Internet Video Phone can talk to
each other only if both users have a computer with a Pentium
processor.
- If you have a SoundBlaster sound card with full-duplex sound
enabled, and you have problems with your computer locking up
when using NetMeeting, you may need to update your Sound-
Blaster drivers.
- You may receive a message in the Audio Tuning Wizard that
explains that your sound card is unsupported. This occurs when
the sound card does not support some of the features required
for it to be supported by NetMeeting. The audio features in
NetMeeting may work even if you get this message, but you might
experience poor audio quality.
If your sound card is unsupported, you might want to contact
the manufacturer to find out if newer sound card drivers are
available.
- If you are experiencing "choppy" full-duplex sound quality, try
switching NetMeeting to half-duplex sound quality. To do this,
carry out the following steps:
1. Make sure that you are not in a NetMeeting call.
2. On the Tools menu, click Options.
3. On the Audio tab, clear the Enable Full Duplex Audio check
box.
It is recommended that you not switch between full-duplex and
half-duplex audio while in a meeting with audio.
- If, during a call, you get half duplex sound even though you
have a full duplex audio card and drivers. This may happen
if your sound card does not support full duplex DirectSound
drivers or has faulty full duplex DirectSound drivers. Contact
your sound card manufacturer for updated DirectSound drivers
or disable the DirectSound functionality in NetMeeting.
To disable DirectSound in NetMeeting, edit the following
registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet
Audio\NacObject\DisableDirectSound
to the following value. "01 00 00 00"
- When in an audio / video call, you may hear the other person's
voice sped up or slowed down. This may happen when one or both
of the participants have an old or incompatible sound driver.
Contact your sound card manufacturer for updated drivers.
- If you are having problems with your audio quality or sound
card when using NetMeeting, the problems could be related to
your hardware configuration or driver installation. To see
the latest support information, click the Help menu, and then
click Online Support.
- If your computer has more than one audio device, you should
make sure that the audio devices selected in the Audio Tuning
Wizard match the selections in the Multimedia properties in
Control Panel.
- If you upgrade your computer's processor, you should re-run
the audio tuning wizard.
- Full-duplex audio might not work with Media Vision Pro Audio
Spectrum 16 sound cards.
- Computers with a 486 processor will not be able to use audio
with other software based on the H.323 audio conferencing
standard over a Dial-Up Networking (modem) connection. They
will be able to use audio with other NetMeeting users over
a Dial-Up Networking connection or with other H.323-based
audio conferencing products over a local area network (LAN).
- When you are in an audio conference using NetMeeting, an
application that has the ability to record sound, such as
Microsoft PowerPoint, will appear to be recording sound
as instructed. However, since NetMeeting is already using
the sound card, the other application is not actually
recording.
- If you have a Tecra 740, you may need to manually set
the microphone volume level in the Multimedia properties
in Control Panel.
- If you experience poor audio quality, try clearing the
Microphone check box and then selecting it again.
- If you are using a Gravis Ultrasound sound card and you
are experiencing choppy audio quality, try the following:
1. Make sure that you are not in a NetMeeting call.
2. On the Tools menu, click Options.
3. On the General tab, in the Network bandwidth section,
select a bandwidth setting that is slower than the
current selection.
HANGING UP
==========
When you hang up, you disconnect anyone you called or anyone
who called you. If the disconnected users have invited or
accepted other users into the meeting, they are also disconnected.
Audio connections between people might not be disconnected.
Warnings and Known Bugs
-----------------------
- If you are using a 56 kps modem in a NetMeeting call with two
or more other people, hanging up may not work correctly.
Switching audio and video during the call may also cause one
or more participants to be disconnected.
VIDEO
=====
- To use the video features of NetMeeting, you need either a
video-capture card and camera or a video camera that connects
through your computer's parallel (printer) port. Sending video
does not work on some computers that have a processor slower
than a Pentium.
- Video is supported only over TCP/IP and with only one other
person at a time.
- Running video in a multiuser meeting can negatively impact
performance on all the computers in the meeting. For example,
opening a video window while sharing an application can make
it difficult for others to take control of the application.
- If you have more than one video device installed, or you have
not properly uninstalled a video device that was previously
installed, you might not be able to use video.
- If your video device is not properly uninstalled and you have
enabled video in NetMeeting, the remaining camera software
may warn you repeatedly that it cannot find the camera.
- If your computer's processor is slower than a Pentium, sending
video may result in poor audio and video quality.
- Computers with a bi-directional (ECP or EPP) parallel port will
perform noticeably better with parallel video cameras than
computers with a unidirectional parallel port.
- Cameras that connect to a video-capture card will use less of
your computer's processor than cameras that connect through
your computer's parallel port. It is recommended that you not
use a color parallel port camera unless your computer is at
least a Pentium 133.
- If you disconnect your camera while using the video features
in NetMeeting, your camera's software may display messages
telling you that the camera is not responding. To disable
these messages, click the Tools menu, click Options, click
Video, and then clear the Automatically Send Video At The
Start Of Each Call check box.
- It is recommended that you not run another program that uses
video while running NetMeeting.
- If some areas of your video window contain the wrong colors,
your camera might be aimed at an area with insufficient light.
Some video drivers might provide a low-light filter option.
- If you are using the video features in a dark area, some
cameras will cause your computer to become extremely slow
and unresponsive.
- If you use a Black and White Connectix Camera, it is
recommended that you use the version 2.11 update (or newer)
of the video drivers. You can download drivers from
http://www.connectix.com.
- Audio input for users of Winnov cameras will automatically be
switched whenever video is in use. If your video is connected
using the MXC connection, the camera input will be used for
audio. If your video is connected using the Composite or
S-Video connection, the Line Input will be used for audio.
- With some cameras, you may be able to reduce CPU usage by
manually adjusting the settings in the Source and Format
dialog boxes instead of letting the video driver software
do it automatically.
GENERAL KNOWN ISSUES
====================
- If you have a beta version of NetShow Player v. 2.0, it
might cause your computer to crash. To fix this, upgrade to
the latest version of NetShow Player and/or deleted the file
VDK32118.ACM from your \windows\system folder.
- You cannot run ReachOut 5.0 on computers on which Microsoft
NetMeeting is installed.
- To find the name that NetMeeting uses as your NetBIOS name,
carry out the following steps:
1. In Control Panel, click the Network icon, and then click the
Identification tab.
2. Select the Computer Name text box.
- If you use User Profiles for multiple users to maintain your
Windows preferences on all the computers on a network, you
might have to run the Audio Tuning Wizard again when you switch
computers.
- Both Microsoft FrontPage and NetMeeting currently use
the same file type (.cnf). NetMeeting uses this file type for
Speed Dials.
- When you are in a meeting, your Clipboard is shared with
everyone else in the meeting. This enables you to paste objects
other people cut or copy to the Clipboard into your local
programs. You can set a system policy that disables Clipboard
sharing.
- If you are running Windows 95 Version 4.00.950B, and you cancel
the Dial-Up Networking dialog box that appears when you start
NetMeeting, NetMeeting appears to stop responding; however,
NetMeeting will work properly after about two minutes. However,
you will not be logged onto the directory server until you manually
connect to your Internet service provider and then on the Call
menu, choose Log On To [your directory server].
- If you create a SpeedDial shortcut, clicking Send To Mail
Recipient will work only if your e-mail program is MAPI-aware
(for example, Microsoft Outlook Express).
- You can return calls by using the History tab only if
the person who called you was using NetMeeting 2.0 or
later.
- If you are using NetMeeting over a 28.8 kbp connection, you may
be able to get better audio and video quality by clicking the
Tools menu, clicking Options, and then choosing ISDN or Local
Area Network from the Network Bandwidth section.
WINDOWS NT ISSUES
=================
- If you use Windows NT, you will be able to share applications
if you have installed Service Pack 3 or later for Windows NT 4.0.
- Enabling Application Sharing on Windows NT may negatively
affect the performance of your display driver. This will affect
the rate at which information is drawn on the screen.
- Some Creative Labs SoundBlaster drivers (specifically those
posted on their Web site January 15, 1997) are not compatible
with NetMeeting. SoundBlaster drivers that come with Windows
NT 4.0. do work with NetMeeting, as do the more recently
posted drivers, which also support full-duplex audio.
- If you use Windows NT, you will experience problems if
you share a 32-bit application and then insert an object
that is a package. This opens the Object Packager, which is
automatically shared and will subsequently fault. This fault
will not cause the original shared application or NetMeeting
to fault, only the Object Packager.
- If you enabled the floating point workaround during
installation of Windows NT on a computer that is equipped
with a flawed Intel Pentium chip, NetMeeting audio quality
will be poor, or audio will not work at all.
- When you share a 16-bit application, all the 16-bit applications
that are running on your computer will also automatically be
shared.
- If you are using NetMeeting on Windows NT and you are unable to
receive a call, restart your computer and try again.
- If you do not have a sound card, you will need to manually
specify the bandwidth of your connection. To do this, click
the Tools menu, click Options, and then click Network Bandwidth.
- You may need to uninstall Dial-Up Networking in order to log
on to a Directory Server via a proxy.
- If, after placing a call, you see a message for more than one
minute that NetMeeting is waiting for a response from the
other person, quit NetMeeting and then try to contact the
person again.
- If you are unable to see a video image in NetMeeting, it is
recommended that you upgrade to DirectDraw 3.0 or newer.
- If you suspend your computer, or if it is set to suspend
automatically, you should quit and then restart NetMeeting
after resuming.
- If you receive a SpeedDial in an e-mail message, your mail
program may convert it to a text (.txt) file. You will be
able to use it as a SpeedDial if you rename it with a .cnf
extension.
