This is the biggest wish I have for my HR20-100 and HR21. Screening out all the PPV channels and channels I don't care about during searches. Using the favorites list is fine for checking the guide. But with all the great HD movies available I'd like to do a search that produces just the channels that I want to set my recorders on. It seems that should be a no brainer and not that hard to do, but if there is a way to do it I haven't figured it out yet.
