ivtv & AMD 760MP chipset
I spent a lot of wondering why several WinTV PVR 150 cards didn't work together properly under Linux ivtv driver - video was getting stuck after 15-30 minutes. Well after I plugged them into an old COMPAQ DL360 server with Intel motherboard the problem disappeared. The conclusion is AMD 760MP and multiple WinTV PVR 150 do not live together.
