I might be talking cross purposes, but I had a full featured DVB-T card which I could never get stable in a variety of systems. However, In my P4 system I have had a lot of corrupt and distorted data transfers (which I don't get in my P3 system) with a budget Nova-T card. In *my* case the Nova-T driver was trying to use quite aggressive PCI burst settings and it appeared the motherboard could just not cope. I had to completely back down the bursting to single dwords before I got something which was stable. This may have absolutely no bearing on your problem, but certainly if you are seeing a corrupt datastream from the card, as opposed to the card crashing and falling over then this is something to consider. I think the 12v issue was more one of the ARM chip crashing and hence no more signal at all from that point? My datastream was so corrupt that it was nothing more than mpeg noise and mplayer would crash after 1-2 seconds trying to play it... However, it seems that PCI bus issues are far less of a problem on the full featured cards, so I think this is unlikely to be your prob?
