I just though I shoud post a litle follow-up on the dvb problems I had. I changed my powersupply from a 300W to 350W and now all my problems seems to be gone. No more weird kernel oops when mythtv is recording and a lot better signal quality on the dvb card. If I run czap, uncorectable errors is always zero no matter what channel I tune to. I have been using the new powersupply for more than a week now, and so far it has not crashed. The powersupply is more important than I first thought when I got the dvb card. I don't know if the problem was caused by not having enough power or that the new powersupply is of better quality, maybe a combination of both. -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
