No (or at least I do not think so). But first an aside ...
Because of the way the Myth GUI hides X, there is no trivial way to look at
STDERR to get a better sense of what is going on. There are perhaps better
workarounds, but this one worked for me. I used Myth's configuration screen
to make the Myth GUI smaller than screen size (600 x440 on a 640x480
display). This gave me access to the X WM's (blackbox) control bar at the
bottom of the screen, which I could then use to switch to the xterms I'd
used to start mythfrontend and mythbackend. THis let me see what STDERR
output each was generating
Now, a guess about your problem -- it is a permissions problem but not with
X. Instead, ordinary-user you does not have access to some device (e.g.,
/dev/dsp) that mplayer needs to work. It (mplayer) tries to tell you this
but you can't see the error output so are stuck with killing X itself (the
only thing you can do, given your restricted access to the X WM).
This part is just a guess. The real advice is that you need to devise a way
to see STDERR to figure out what is really up. Perhaps others can suggest
better workarounds than this fairly clumsy and ugly one I've contrived.
