I watched revolt of PE so much as a kid that I pretty much know it by heart. I remember watching it with sister on the DVD some months back and I'm sure there was a scene in it that isn't on my childhood VHS. The VHS version I have is the one with ice cream wars, in the cardboard sleeve. I think they may be extra because of splitting the episode...or mine is missing because of splitting the ep...not sure, can't quite remember. It's not a big scene but I am sure it is there (or I'm going mad )

Dreamland - why not?

I'm not sure that MLP ever aired on TV in the 1980s in the UK, does anyone from here know if it did? I always feel like all MLP eps came to us on VHS not on TV because I watched a lot of kids cartoons as a kid and never MLP. It was played on one of the cable channels in the middle 1990s, I think Sky 1 - because a friend of my sister's had that channel and recorded them all and my sister borrowed the videos...but I don't remember it ever airing before that. (Or maybe because I was a comic kid i wasn't interested, but I doubt that because I was obsessed with Revolt of PE and Ice Cream Wars at one point).

Movie came out in cinemas here, but I don't recall the actual series. So it might be that when they went to VHS - and all the VHS here seem to have been put together by different organisations - there was some information missing as to what it was about (or they thought dreamland sounded cuter).

As for the DVD errors -  the Jem DVD has soundtrack errors in the World Hunger Shindig episode and, I think, Starbright 1. Doesn't surprise me that the pony one has animation ones.
