I've been watching ABC1, E4, Channel4 and all the ITV channels (UK). Every time the adverts come on MP comes up and says 'Channel Scrambled' and I get a black screen but I can still hear the audio. If I restart MP I can watch the adverts but as soon as the show comes back on the same thing happened. Has anyone experienced this problem and has a solution.

It was because I was using the MainConcept (Hauppauge) MPEG Video Decoder.
I found that the decoder could'nt handle the change from 4:3 to 16:9 that occurs when the particular station switches to commercials.
