I think you ought to probe that a bit more.  We are using XFS on dozens
of servers here, all of which should be seeing much more rigorous usage
than MythTV, and have never had such a problem.

Things to consider:

1) This could actually be a symptom of a hardware problem

2) What kernel are you using?  If it isn't one from kernel.org, your
   distribution vendor may have patched XFS and broken it

We have had problems with JFS and reiser (all versions) relating to data
integrity after a crash.  XFS and ext3 are the only journal ones I'd
call reliable.  Note that XFS crash sematics are only as reliable as
ext3 after 2.6.17.
