Thanks for your reply. Your on the right lines. It recorded only the first 3 minutes of the programme and the timer bar moved rapidly across the screen from left to right on playback. I didn't try to play again as the clock recorder clearly showed it had only recorded 3 minutes worth. With regards to the yellow and black symbol I seem to recall 2 horizontal yellow lines crossed with a black line at about 45 degree angle. I once had a chart showing all the symbols and their meanings but it has gone astray and I have been unable to find a copy anywhere on google. I've no longer got the programme details to hand but I do think it was recorded on one of the free to view channels and not BBC, ITV or Channel 4/5. Any further help would be most appreciated.Photo?
