SYMPTOMS
When I try to make NetShow video and audio files for streaming via 28.8 modems and keeping the bitrate to within 20-23 Kbps, I can not get the bitrate to what I need.

WORKAROUND
The audio is adding more than you are accounting for. Try to keep the video using MPEG4 in the 10-11kbs range and usually either 11khz FHG or the MSNAudio codecs, depending on the media.

You may need to specify a larger value than the default for the -leadtime parameter when you use VIDTOASF. This parameter specifies how much data to buffer or preload before the clip begins to render. A larger leadtime can slightly reduce the bandwidth needed.

You can also use VIVO's Active Producer or Sound Forge from Sonic Foundry.
