The new powersupply fixed the bad reception.
The only other problems I had was random lockups every few days when I used
redhat9 with 2.4 kernel, but I belive they were caused by my analog bttv
card.
After I upgraded to fedora fc2 I haven't had any lockups, instead the bttv
sometimes complains in the syslog and the picture goes all black, it only
happends at the start of a recording that mythtv does.

Some dvb channels do have uncorrectable errors which causes audio and video
corruption, but it's a lot less with the new powerupply.
