I think this should show up as system time in top, but I see 50% idle.
I'm running LVM across two disks, no RAID. Should be fast enough as the
data rates aren't really very high - no more than 20Mbit/second, because
that's all that can come in off the air.

I forgot to mention: Xine on another system can't play back the recorded
file properly either.

Non-HD works perfectly for me, PIP, multiple recordings while playing
