[QUOTE="grubi, post: 178213, member: 52476"] I did further research about the issue in the web and found some interresting things. MP is not the only one having problems with it. I found a thread in the German "Dreambox" forum where you can read that Dreambox users have the same problem. Interrestingly they also supplied the reason why. The broadcaster send the AC3 audio track between 60 and 160 ms earlier than the picture (different providers choose different delays) to give the devices enough time for processing the AC3 signal. As receivers are not equal in processing speed you then have to delay audio again in your setup to get into sync again. They choose this way as it is only possible to delay audio but not to speed it up. This gives also the explanation why this is only seen on AC3 and not mpeg audio because there is no processing necessary. The devs of the Dreambox implement an audio delay you can configure on a per channel basis. I strongly vote for a similar configuration option in MP. Regards, grubi.
