Hi,

I have an issue I cannot get solved. I am using MP 1.1.3 with StreamedMP in a single seat configuration. My TV card is a DD DuoFlex CT and I have one cable tuner and one DVB-T tuner enabled - no CI.

The TV-card works just fine and finds all available tv stations. Playback of live tv has one huge issue though: you never get lip synch fine. When you first start live TV from the MP homescreen, the playback is fine. However, changing any channels leads to terrible issues with lip synch. The TV picture is always behind the speech. I can correct this by pausing the program for a few seconds or rewind a bit. The program will then be played fine for some time until it starts to loose synchronisation again. None of these issue occur when I playback video in MP.

My setup is a Intel Core 2 Duo E6700 with win7 and 2GB ram (1GB recently assigned as a ram disk for TV buffering - no differences in behaviour though). I have tried all kinds of codecs and I am mostly using ffdshow. I tried to use re-clock but could not get any better behavior. I am at my office now but will post a log over the weekend.

Did anybody encounter a similar behavior. What could it be?

Thanks in advance!

Best regards,
Andy

    Hi and welcome Andy :)
    My first guess would be codec problems and/or the refresh rate of the content not matching the refresh rate of your monitor/TV. Does it happen with all channels, or just some?
