If you want, I can upload an episode of what I'm refering to so you can se what it exactly is (or it would be ilegal? if it's ilegal, I can send it if you send me an MP, and if it's illegal or against forum rules too, then sorry, I will not upload it).
I did convert an episode to digital when I discovered what it was, then synched it with the video to see if it exactly fits (and it did).
Sadly, those are not "tapes" that could be easily converted. Those are old big reels with only audio track, no video. They have to be converted analogicaly with a revox struder (an expensive machine) to digital, not just a normal VHS, then synched to the episode itself. That's why I also asked if those are of any value, cause of the cost of converting them (and if it is really of interest of anyone, I may try to find more episodes, but now only have the ones I mentioned and don't want to do useless job, of couse

).
