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
