One thing to try. What video connections are you using? I was using both S-Video(To TV)and Composite/RCA(To DVD Recorder) and I was getting problems just like yours but only on USA, SciFi, Disc. Home and some others but most channels were fine.
After reading here about others having problems with using both video out connections I took out the composite and the problems went away. Every time I put that one yellow cable in the channel would pixelate.
Hope this might help.
