Before the patch your sample played horribly on my system and with the patch it's near perfect. So even though you still see some a/v sync problem did the patch improve playback any? I did see one very brief instance where the timecodes went a little wacky but it was extremely brief and recovered properly.
Could you please provide another log with -v playback,timestamp?
