I'm doing a comprehensive article on the many different versions of "Superman" (just the first film only) that have been released since 1978, among them the VHS, LD, and DVD formats. I clearly remember that the film had been released in a 2-disc LD-style videodisc format, as I'd seen it a few months back at the flea market. If I remember correctly, it was called Video CED, though I could be mistaken. From what I remember, it required sliding the disc and the sleeve into a disc player, then sliding the disc out before the start of the movie. Can anyone provide additional information on this format? What were some other films, for example, that were released in this format? How much running time was typically on each side of a disc? What was the audio/video quality like? For a widescreen film like "Superman", was there any pan-scan of the film required, or were they able to do it in widescreen format? Any and all information would be greatly appreciated, as I would like to have my facts together and in order to include in the article. Many thanks, guys!
