The DVDR/VCR is going back, maybe even with a blank cassette in the video tray as the remote and the manual button wouldn't eject the tape after repeated tries!
I visited my local Comet today and explained how I had the DVR/VCR set up and the technician on hand told me that I'd installed it correctly, daisy-chaining the devices.I've installed similar equipment before but this Toshiba model didn't do anything it was supposed to.I was very disappointed.
I went back home, got out my LG VCR again, connected my Sky box & TV, tuned in Sky and taped an hour of TV without
any distortions in picture or sound.

I haven't a clue why I had the problem in the first place but I'm happy that I have a recordable picture again.I get a
fantastic picture on my VCR and as I don't get a lot of time to watch TV it serves its purpose.
