I did the same thing with the tape I found. I was thinking of recording the VHS sound and the video from the DVD back to DVD or VHS. There are 2 versions of the tape, one in SP and the other the horrid EP mode. I own both as well as the restored version on sealed VHS I found for 99 cents. And there is also a Beta tape version. I'm still on the hunt for that one. As far as I can tell the original was never released on Laser Disc or CED formats.
