Hello everybody...

i have another problem with MP RC3 and watching XVID Videos.

From time to time my HTPC crashes while watching XVID Videos... From one second to another the picture becomes black and the sound starts looping...

Does anybody else has a similar problem?

Does anybody know a solution for my problem?

Thanks in advance

sincerely

Sebastian
