[MPlayer-users] RealVideo desync

I'm getting audio desync that gets progressively worse (ie, can't just
fix with constant offset) with some RealMedia files. The problem exists
in current CVS, and with both the rp8 and rp9 codecs. Mplayer -v log is
attached, and the file (KKnJ19-small.rm) is being uploaded to incoming.

Note also that this file works just fine with Realplayer.
