I use a 2TB WDC WD2003FYYS-02W0B1 for my recording drive with XFS. Works 
just fine.  A have a second 2TB drive for my video and music storage 
using ext3 (this was initially setup on an older mythtv system that did 
not support ext4).  My thought was that ext[34] would be better for long 
term storage due to the journal (ie, tolerate power failures better), 
where XFS was better for recordings (ie performance).  The irony is I 
back up the video and music storage on a backup server, but not my 
recordings.

The one thing I did notice is that with ext[34], you lose some drive 
space for the journal that you do not with XFS, so you can store more 
user data on the same drive with XFS.  Probably not enough to be a 
deciding factor, though ... just get a larger capacity drive.
