Wow...as someone who understands MySQL well and *really* likes having
access to the database, I have to tell you I really don't like that
one at all.  As a matter of fact, having access to that data is in
fact one of the (many) things I prefer about MythTV to proprietary

What happens in that situation with stuff like optimizing, database
backups etc if the backend process is the only thing that has access
to the database.  I don't know if anyone actually does this, but it
would also make having the DB on a separate server impossible, which
I'd think is doable now.

Seriously...I really appreciate all the work done by all the devs and
don't want to sound negative, but between this, the removal of
external player support and mandatory storage groups in mythvideo, I'm
not sure I can remember the last time I heard about an upcoming MythTV
change that I actually liked...it's really really starting to bring me
down in a big way.
