TV stutters, don't know why...

[Argbeil]

Hi, I've done a fresh install of WinXP and MP, I did download the newest drivers and installed all Updates. But TV is stuttering imediatly after starting, Video+Audio stops after ca. 5s for about 1s and then continues normaly for about 5s.

I've tryed to change Codecs, Resolutions etc., disabled Virus Scanner but nothing works. Watching TV with the bundled Terratec Applications works fine, signal quality shows between 95 - 99 percent there.

Any Idea?

Cheers,
Manu

By the way, I'm using Media Player 11, could this have some effect?
