I am pretty sure that zfs-fuse is not ready for prime time. There  
have been reports of corruption issues and the author has even stated  
on his blog that "As for performance, well.. zfs-fuse is slow right  
now, but it will certainly improve. I haven't even started to  
seriously look at performance."
ZFS is a great filesystem but I would hold off recommending anyone  
use zfs-fuse on a production machine until it becomes a little more  

If mythtv (and ivtv, etc..) ran on solaris then I would definitely  
try using ZFS.
