Comment(by majost at lagparty.org):

 HD h264 content still appears to have audio sync issues. The issue may be
 with the version of ffmpeg in the fixes branch. However, previously I was
 able to play the content -- but the sound was severely out of sync, with
 the patch applied mythfrontend crashes when it attempts to resync the
 audio.

 Despite compiling with --enable-symbol-visibility and --compile-
 type=debug, I was unable to run the frontend with debugging symbols in
 gdb. I have included a backtrack from windows crash manager and a
 (limited) gdb backtrace.
