All the movies, except #1, are definitely available OAR with English in Europe. In Japan 1-3 come with dual audio (2 is a bit of a noobjob and 3 is an alternate cut); 4-5 have issues that make DA impossible (4 is a radically different cut, 5 just has one big cut right at the beginning). After that it's easy enough to synch them up (I've done 6-10).

I've got various projects going related to Pokémon myself (I'm trying to fansub it but keep having translators walk on me; I'm also trying to improve on the DVDs). Actually, the R1 DVDs are better than VHS quality. (They do seem a bit more compressed than the R1 singles, though, which I'm trying to acquire.) The season 2 (Orange Islands) and 5 sets are crammed.

Now, as for edits - there's not a lot of edits until you get to Johto League Champions.

R2s? I wish! I think everyone's trying to find R2s of Pokémon but there really aren't any. A few eps were released shorn of their opening and closing on special DVDs but otherwise you're only likely to find eps. 119-138, 207 and 245 of the original series on R2. In many cases, the R1 is in fact the best quality video out there. Depressing, isn't it? :(

The second and third series have better DVD coverage but almost the whole thing is rental only. A friend of mine has been collecting them from secondhand sources. They're not exactly easy to come by.
