Interesting about recovering teletext pages from VHS tapes. I don't know if it works on tv's today but back in the 90's I remember pressing the text button whilst watching videos recorded from tv & you could sometimes ( not always ) see very scrambled teletext pages from the day/time you made the recording. If you pressed 888 you could see bits of subtitles. First time I noticed it I thought the tv was haunted.
Tried that myself Arthur depending upon the tapes quality you'd sometimes see more teletext than on others.
Thanks for the reports lads was very interested in what Dick Fiddy had to say about getting rare programmes on DVD. Reckon on demand programming could be a solution but again will they want to host a obscure programme when the big £'s are in the popular stuff.
