I wish there were better answers...
1) I don't think you can stop the unit from changing channels as its starting and stopping the record, writing new files, etc. Ours is on stratight cable without a tuner box and this same situation seems to go fairly smooth. (although there's times the credits of one show end up in the recording of the next) So if you can live with one Replay hooked to basic cable, that might help.
2) If you plan to write one show out to DVD eventually, you might just make a manual recording of the entire evening's block of shows. Then when you are cutting out commercials to write to DVD you can also pick the exact frame you want to call the episode's start and end.
