You might get prebuffering pauses while playing back those recordings
that exist on the drive with MySQL, but they'll be transient and won't
affect recording.

Yep.  Then again, you can use my approach--don't put the Myth backend
/or/ frontend in the same room as the TV.  My frontend is in the world's
ugliest case and is extremely loud, but I can't hear it from the room
with my TV.  Or, even if you put an extra disk in the backend and put it
in a different room, and then make a small, quiet frontend (or use your
existing box as the small, quiet frontend), you don't have any
dependency issues--except while actually watching TV.
