Nope. I can play 44,100 Hz plain audio files just fine. I don't recall 
precisely what I was using to play back the problem files -- it could have 
been Myth's internal player or an external player such as mplayer, but it was 
definitely causing me problems. I also recall that I burned the file to a 
DVD+RW and had the same problem on a standalone DVD player. It's entirely 
possible that the original file itself was broken in some way.

In any event, I ultimately fixed that specific problem; I only mentioned it 
because I thought it was possible that something similar was at work for the 
OP. Testing the audio encoding frequency should only take a couple of 
minutes.
