Either Reiser or XFS provides better performance than ext3 (and ext2) for 
large files, such as MythTV recordings.

Yes, journaling does require a little bit more processing power, but not a 
huge amount more. I'd say the performance benefits of either Reiser or XFS 
outweigh the very tiny processing hit for journaling. I can't recall offhand 
which of the journaling systems requires the least cpu time, but the amount 
is pretty trivial for all of them. Heck, try 'em all out, see what works best 
for you. :)

(Btw, I use XFS).
