There is/was one site selling Droids DVD(s?), in Canada if I remember correctly. I'm not sure what was the source for this but that's considered to be the best one out there. Too bad they won't ship to Europe. It also cost something like $30.

Anyways, I'd be interested in these. I liked Droids as a kid, I also have the original rental videos (which are subtitled) but they didn't release Mungo episodes or the Great Heep. I also recorded almost all of them from TV and they were dubbed, would be cool to get the audio from there (too bad it's not stereo) and add those to a proper video. Also, being a kid, I didn't understand to put a few minutes extra when recording them so almost all of them are missing a minute or two from the end. :(
