Is it a dedicated-to-MythTV-only box? If so, you might encounter far 
less problems using some distribution other than SuSE. I like SuSE 
quite a bit myself, but it just ain't the greatest for this particular 
project.

Hm...

What TV card exactly was that? Not that it would help me any. I haven't 
a clue what causes those errors. :)

Hm... What sound card, and what drivers? Most importantly, ALSA or OSS? 
I presume ALSA, as SuSE ships it by default, if I recall correctly, but 
I'm not sure how recent a version you'd have if you're running SuSE 
8.1. You might have to upgrade your ALSA drivers.

Oy. Good question. :) Check on the sound card drivers, and go from 
there, I guess...
