The actual film was not changed, the titles remain as they were in 1981, rather the packaging was altered on VHS (?) and DVD.
There is probably nothing to make it a candidate for a fan preservation project, unless it turns out that the snake reflection, boulder guide track etc... are still there. The content of the film, edit, picture, sound etc. are still as they always were in the 2003 DVD's, but since this broadcast predates the DVD, it may have none of the digital enhancements levied for the release - in which case, would make a dandy hi-def 25th Anniversary theatrical preservation project. Or I could be splitting hairs...I just want to see this thing.
