My box is a barebone. I have a couple of good sound cards lying around
here but the only PCI slot is occupied by the tv card.

Seems to be something else here. It's not always there. If there is a
hiss it is always with the same channels but not all the time. The
on-board sound is a SIS 7something.
There seems to be a difference with high or medium audio quality
encoding but I cannot see a pattern so I think I'll have to run some
I've also heard about issues with the alsa module for that chip. Maybe
I'll try a 2.6.3 Kernel.

I never had any stutter with that box. It was a problem with my test
setup on my desktop machine (Epox KTA8+ pro, Athlon XP 1600, Ati Rage
128, Hauppauge WinTV PCI, SB64, 1 Gig RAM) until I stopped almost
everything but mythtv.
