If I'm not mistaken..you can get this card to capture in .avi, divx or whatever. There is just some work involved and of course, your cpu will be doing the job. An xp s/b fine. VurtualDub will capture. I had the WinTv 401 and I was capturing in divx..well not much. I never worked very hard at it. But it was doable. You can get a different driver from sourceforge as I believe this uses the Conexant bt 878 chip. Link
