Since 0.13 I have been experiencing tearing while watching TV with timeshifting turned off. Tearing will disappear when timeshifting is turned on.

Tearing happens when the screen refresh is out of sync with the source. This is most visible during pans, where some of the previous frame is still visible in the lower part of the picture. If we were panning on a tower, it would look something like this:

It should look like this

Many others have reported this on the MP forums, but have been chased away by developers claiming this have something to do with drivers, codecs and their refresh rate. The mere fact that this problem does not occur when timeshifting is turned on, makes all such considerations irrelevant.

I will generate log-files when I get home from work.

i get the best results with the build in codec mpeg2dec and the winDVD codec.

Why is the Nvidia codec not the best choice? It lowers my CPU use drastically, and provides me with the best image quality of all the codecs I have tested. In my original post I clearly state that this was not a problem in earlier versions and is not a problem when timeshifting is turned on. Why do you then think that the Nvidia codec is to blame?

    because of my personal experience.
    i was never satisfied with the image quality i got with the nvidia codecs. the other problem was that with this codecs i got the most crashes (mediaportal and 3 other htpc programms).

    i found out that windvd (exept version 7 that is stil causeing wired problems) and mpegdec2 were the best codecs for the most dvb setups.

    it sounds strange that this problems only appear when timeshifting is off.
    but i belief you that this is happening.
