Well, I guess it wasn't that simple. I forgot I was using an alternate
a52 plugin, so I reconfigured my alsa-plugins to use the built-in alsa
a52 plugin, and that solved part of the problem. Now I'm unable to
reproduce the freeze with aplay or mplayer, but mythtv still doesn't
work. I can run the speaker test in the Audio setup and it plays
static over the left and right channels and uses my upmixing devices
correctly. I also checked MythMusic and it works fine and upmixes
correctly, too. However, playing recordings doesn't work. The behavior
is different, now, too--it shows the first frame of video and never
advances and there's no audio (but it does respond to Escape). The
logged error is different now, too, and a google search of the logged
messages doesn't show any similar problems. Here's the log now:

As you can see, I let it sit there for about 10 seconds before I
escaped back to the Watch Recordings screen (I tested earlier and let
it sit about 30+ seconds, same result).
So... now what?
