SUMMARY
Windows 95 video capture drivers must be 16-bit to work with Video For Windows.

MORE INFORMATION
Under Windows 95, video capture drivers cannot be 32-bit if you want them to communicate with Video For Windows. Video For Windows requires 16-bit video capture drivers. It is possible for the 16-bit video capture driver to thunk to a 32-bit dll, but Video For Windows assumes the video capture driver is 16-bit. If you want to use a 32-bit video capture driver, then you cannot use Video For Windows API's and you must establish your own interface between the application and 32-bit video capture driver.

You can use MSVC 1.5x to build video capture drivers since it is a 16-bit compiler. MSVC 2.0 and above are 32-bit compilers.
