Hmmm. I was looking on the list because I have a bttv based card (Magic TV from Skywell), a Savage4 and a Via Apolo Pro chip and my linux locks up after some seconds. The best way to lock it is moving the window with the tv image. :( The only difference is that I have XFree86 4.1 It is no hardware bug -i think- because it is working on win98 (not on Win 2K though). Maybe the Xfree86 ?
