rojash is probably right, I have a panny dvd recorder and it tells you that the tv programs you want to watch are on at the same time and on a different channel, could be 5 mins or the whole program, depends when they start and finish. It's not a problem when you are recording progs on the same channel, only sometimes when selecting more than one channel. The recorder is fine. Or.... have you set it to record programs in the past and left the details in the recorder? Check out what's stored in the timer memory in case it's cluttered. Mine keeps it's memory of stuff I forgot to press the timer button for and it doesn't go away until you manually clear it. Hope this helps..Dagman
