This is a backup database for testing purposes, and has nothing to do
with the myth installation.  As Torfinn says, it's a nuisance that it
won't go past it.  I solved the issue by stopping the local mysqld,
setting up mythfrontend with the remote database, then starting mysqld
again.

This is the state of modern multimedia software, I suppose.  SIGSGEVs
in running programs are always a problem.

I haven't seen any stuttering.  But I barely watch live TV at all, so
that doesn't mean much.

What I have seen, both on live TV and recordings, is that sometimes
the front end will trip over itself and not display anything except
for the screen overlays.  Under these circumstances it seems to hang,
but tcpdump shows that it's actually transferring data (p will stop
and start the stream, for example).  It's doing it right now, with the
rather unusual situation of displaying a completely transparent
(invisible) full-screen window.  I can iconify it and deiconify it,
but apart from the fact that it also grabs focus when deiconified,
that's the only way I know it's there.  Pressing ESC gets out of it.
Weird.  I don't know how much this has to do with the port, though.
I'll investigate further.  And, of course, when I stop it I get:

  [1]+  Segmentation fault: 11  (core dumped) mythfrontend
