There are full BD-25 versions available, good luck finding them though. I've been trying to download it for days. It's going at about 60 KB/s.
I'd just skip it and get the ones on the bay, and might actually do that for episodes 2 and 3, but for 1 he only has his v2 up which removes sidious from the film, so I'm trying to download v1 BD25 from usenet. Should be done in 2 days...
