Problems with recorded TV playing

[amir77a]

Hi,

I am using Vista Media Center.

I have problem to play any recorded TV content including the sample files.

It is often freezing for half a second, and sometimes it looses the video/audio sync for a few seconds.

If I play the same file using Nero Show it is OK.

Any other media are playing hassle free.

Any ideas how tp solve this annoying problem?

Thanks,
Amir.
