I have a strange problem: xawtv (3.61) and bttv (0.7.77) are causing hard freezes of my machine (Athlon 1.2GHz, 512MB RAM not overclocked). The card is number 38 (as autodetected), I'm using tuner type=3, because that is what seems to work best with scantv, even though the SECAM in the tuner's name worries me, since we have PAL here. I also tried type=7, and that didn't seem to help any). As soon as I start watching TV (sometimes after one second, sometimes after as many as 30 seconds), the machine freezes hard. The sound continues to play, but the mouse is frozen, the keyboard unresponsive and remote login impossible. In other words, only pressing the reset button gets me anywhere. The weird thing is, when I first set up my machine, I had this problem (with bttv from the 2.4.9 kernel), but then I installed a new bttv and the problem went away. Unfortunately, I accidentaly lost my partition, and now I can't seem to duplicate whatever I did before that fixed this. Note that if I use the -remote switch, the problem does not occur. However, the -nodga, -novm and -noxv switches to not help. I am using the latest Xfree86-4.1 (from debian unstable). Does anybody have any ideas what could be at fault here? Is the the X server? Is it bttv? Is it the TV card's fault?

I KNOW I had it working before I blew off the partition. I can't understand why it doesn't work now. I'll be gratefull for any hints.
