Thanks for the reply. I've done that a few times but one of the recordings ended eight minutes before the end of the movie. What seems to be happening is the schedule says the movie is 1 hr 43 mins. When you watch it you find that the recording starts a minute or two into the end of the previous movie. Then come all the promos and the intro of the next movie (the one I want to record) because of that extra time in the beginning the end of the move is clipped. Sometimes I go the end of the movie to see if it's been clipped. If it has it's too late.
I need some tech person at TCM to answer the question.
