Locally mounted non-raid.  It was Raid 5 for a while but switched it to 
a non-raid non-lvm setup in an attempt to fix the problem, and I will 
say that it got a little better.

Deinterlace filter is Kernel.   No XvMC.  And a Nvidia 5200 with driver 
7174.  When watching liveTV my CPU show about 90% idle.

Also, didn't include it above (oops) the lockups occur with both my 
pvr350 and HD-3000 but normally the HD-3000 shows an error screen saying 
"an error was encountered  while displaying video" and in-case it 
matters the ivtv drivers at 0.6.3.  But almost all livetv viewing is on 
the 350.

Thanks
