Similar to Rudy, I'm using XFS with SW RAID10 (4 drives, 600MB), and
previously had it as RAID5 (but it wasn't fast enough), and have had
no problems. 3 HD tuners and a PVR150.

I do run the XFS check/optimize apps "nightly"(4am) to keep the health
of the partition up, though I only recently started doing this and
only to be safe, I hadn't had issues before.
