I see no errors, exept for a issue with CNN/Discovery on 1west,
the audio bitrate is misdetected by libavcodec,
and audio is played to fast (dual speed).
(No errors reported though)

If you tune the card with s/t/czap and play using mplayer, does it work
then?

This happens here too, I think the trouble is in the osd.cpp (which needs a
rewrite to support caching of not-prescaled-images).

I had some problems when I got my Nexus-S, and ended up replacing the
motherboard to http://home.no/mythbox (all problems gone).

Acpi == off?
PCI Latency setting needs to be high (128->).
Upgraded bios?
Tried ripping out anything but the DVB card?
