When changing to a channel with AC3 sound (through spdif) audio is out of sync often. Skipping forward or back in the TS buffer fix the issue, maybe not 100% but so close it could be speaker setup.

Also AC3 via SPDIF does not work correctly with Intervideo windvd7 codec. It's almost like it's an "under water" effect on the sound.

    What is the CPU usage during this? Do you see any 100% peak when you switch?

    Trying to clean up forum, so we can focus on the real bugs.

    It seemed that your problem was mainly codec related, so not a bug in MediaPortal.

    But the main reason I classified you, was because you didn't reply, so I assumed in the last CVS your issue got solved. But I'll put you back as unconfirmed bug, because so far nobody else has been able to confirm this one.

    So please see if you can target down the problem, try other codecs/settings/etc. And of course use latest CVS.

    I installed a SVN yesterday, and so far it seems very stable, havn't tested much yet. I noticed that normal sound was a little off sync, but I think that was the broadcast, happend once in a while on my STB as well.

    For some reason tvguide (webepg) import doesn't work. The tvguide.xml is full of info, but nothing gets imported.

    Hi,
    The webepg works here, had a complete new install of MP yesterday & runned a new webepg now to test, everything works here.
    Take a look in setup & check if anything it's changed & select "Remove all programs from TV database". After that you can run import TV guide one more time, if not start a new thread about webepg issue.

    Regards
    Roy

    I found the EPG error, the path to the XML file is "hardcoded" in configuration.exe, so when I copied the "MPRC3" folder (clean install) over to a "CVS" folder that I could apply CVS on and still keep the fresh RC3, the path to the XML file was still pointing to the path where it was originally installed.

    Never had this problem before though. And easy fix would be to use %mediaportalfolder%/xmltv rather than a complete path, but then again, that would break the ability to use a common tvguide.xml file for different installations.

    i have noticed a simmilar issue with some TV-Shows. but they are broadcasted out of sync.

    so this is fixed?
