last time i tried cyberlink codec and audio was in sync but overall playback shutters badly so not watchable.. so it is the codec that is causing the audio delay on ati encoder... i have tried more codecs but others did not work.. only ati and cyberlink are working but not fine ... I don't have the log as i have uninstalled mediaportal now as my pc was unstable and slow. will try maybe another time. thx for your replies and any other suggestions are mostly welcomed.
