After try several different approaches, I have created a OS/2 program designed capturing the video from BTTV for OS/2. BTTV is a port of the Linux driver for BT8X8 TV-Cards. Unlike most OS/2 TV applications, it does
support NTSC.
Unfortunately the methods it uses are far from ideal. To capture video it screen captures the video window of the BTTV TV application. It captures audio from the line-in of your sound card, but it does not include it in the AVI file, but stores it in a separate wav file.
However, since it captures from the screen, it could be used to capture video off other applications.
It is distributed under the GPL and is written in Virtual Pascal.
