Hi Buddy -
RT subvolumes are "sort of" implemented, but not at all well tested.
It's on the todo list. If you can run your oops through ksymoops it
would be more helpful, or I'll test it out here when I get a moment.

XFS without RT has worked just fine for me for video capture (from a
miniDV camera, to a 10k RPM scsi disk). I'd suggest a
larger-than-normal log (mkfs option) and "logbufs=8" as a mount option.
See if that will keep up with your needs...
