Can you please post a screenshot and maybe attach Avast detection log ?


I attached the warning.log file. The lines corresponding to my svn installation are the last ones.

I paste here one of them:

    I'm also having a bit of video trouble... it's just odd and doesn't effect all my movies.

    I just finished putting a batch of DVDs on my HTPC as .iso's. When I play them, some play through just fine, no problems with menus or anything. Others, on the other hand, will sometimes start with no picture, just sound. It happens mosly at breaks between, promo film and menu, or menu and main movie, or intro logos and THX screen. This is with the MPV codec. It makes no difference when I skip to the next section. If that section wants to start without a picture, it will.

    All I have to do is stop (not pause) the movie and start it again at the same spot, then picture is back with sound. If I stop and start after the beginning of the actual movie, then the picture is back and there is no further issue through the movie. I also can, once I get to the main menu, go to the first scene in the scene selection... and then there is no problem. It's really anoying.

    Anybody who knows anything about videos please explain...



    also when I use the PowerDVD 7 codec I just get black screen, no matter what. With FFDShow it locked up my machine after showing only blank screen. I had to reset.

    Don't have time to test much today... cleaning house before family arrives for a week-long holiday.

    I'm still on svn 19453, havn't updated yet, I've just started having problems with channel change, not changing ac3 with ffdshow. Video freeze no sound.

    I skipped the last svn due to some nasty bugs. With this svn I can't switch from an HDTV (H264) to an SD-channel (MPEG2) anymore. The picture freezes but I can go back to the MyTV menu. After switching TV off/on the graph starts again and the selected SD-channel works.

    I tried different codecs (CoreAVC and PowerDVD8-H264) for AVC and MPEG2, but the behaviour remains the same. The svn two weeks ago works good for me.

    EDIT: Now I just updated only the TV-Server. Works good with the two weeks old svn from Mediaportal. So the bug is located in the present Mediaportal-svn.
    I can confirm the pieture freeze on h264->mpeg2 behaviour

    I don't know if this is relevant or not. I am using RC1 and SVN 19510.
    Recently, i too had problems playing certain MP4 files which use to work just fine. In order to fix the problem, i had to re-install ffdshow tryouts ( the latest version ).
