mplayer appears to work fairly well.  I've never really wanted the
menus or super omniphonic stereo sound, which is the usual failing
point with these things.

It would be interesting offering dvd support in mythtv.  You're in the
US, no?

Well, one could trivially launch mozilla/konqueror or mame; add a
button or two for X10 light dimming; or any number of other things.

Yeah, I'll play around more tonight, too.  It's really the darndest
thing.

Qt might be discriminating against synthetic events, although why some
would work and others not I don't get.

Silly x86.  Grr.

I could offer you code to say "I'm being debugged, behave
differently," but I'd rather not curse you with heisenbugs.

No, I don't think so.  I get a number of "strange error flushing
buffers", but this appears to be coming out of the recording side,
which aside from the message is working just fine.  AFAICT there are
no other messages at all besides the state changes.

Here's from all of yesterday and probably some of the day before:
