Yes, I mentioned it in my previous post.

Strange, for me, vanilla MPlayer detects 22050 Hz instead of correct 
44100. The patch makes the decoder return samplerate and other stuff 
based on the second frame, as in the previous versions which skipped it.

tv capture using mencoder, then a part was cut out using avidemux. I 
have more files produced by the same means, all of them work. I agree 
the file is buggy, but older mplayer releases had no trouble.

I didn't try it yet.
