Follow-up question: I recently enabled AC3 playback with an SBLive! Works
great
with an actual AC3 rip. However, I get the same 0x55 codec complaint when
playing
an MP3 movie. Forcing it with -ac mp3 works, even though it's still playing
through the digital output on the SBLive!

So the question is... why? Why doesn't the codec recognition work in this
case?
It's clearly not a handling problem, since the MP3 files play just fine if
you
tell mplayer which codec to use...

Is this done for a reason?
