Yep, the comma is there for me. And mplayer log is exactly the same,
no matter if it's sarted from mythfrontend or from a terminal window.
But if it's started from a terminal window, I can watch a movie, and
if it's started from mythfrontend - I can only watch a slide show by
pressing FastForward continuously...

Is there any way to trace what the problem is? Running mythfrontend
with '-v playback' doesn't provide any additional information in this
