I checked it out, and I have the same results. When I explicitly tell mplayer to use '-ao oss' there is no sync issue. When I have '-ao alsa', the audio and video don't match (audio too late). I forgot to check the CPU load, but its probably not very high (2.4 GHz P4). I still want to go back to the older alsa and make sure its a problem with the new alsa and not with both. -Adam
