Can those who had problems with audio/video synchronization on some files test these files with the latest version mplayer_1.0rc1-maemo.14.800 again and report results? I have rewritten mp3 audio passthrough fake decoder to make audio/video work better with variable bitrate audio. On the other hand, that's relatively a lot of changes, so testing is required to ensure that nothing else got broken. Please don't hesitate and report any problems.
