Hi folks, I'm using a hauppauge pvr-350 tv-card and ivtv 0.3.6f. It
appears to be correctly set up because I can watch it with mplayer and
change channels with ptune.pl, etc....I'm running an SMP opteron box
with tyan s2882 motherboard and all seems well.
I've followed the essence of a few tutorials I've found online...too
many to mention. I've set up and I can run the backend with no trouble
but I cannot Watch TV at all. I get an immediate Segmentation Fault.

> Here's the backend output:

> I don't have anything fancy in my xorg.conf because I want to watch tv
on my monitor. My package version is mythtv-0.17.
Anything else? Let me know and I'll post more info ASAP.
Thanks!
