I found everything I needed for the video card (and tuner) in /usr/src/linux/Documentation/video4linux/bttv.
Kwintv (now QTview) seems nice. --------------------------------------------------------------------------------------------------------------------- then I assume you could email me a copy of your modules.conf (and any other needed config files) and my ati aiw 7500 will "just work"? (btw what kernel version[s] do you have this working on?)
