I don’t understand why the file is so enormous.
The file should be about 20-25GB. The only way to retain the high quality that an HD encode can give (that you said you wanted) is to give the file a high enough bit-rate to make it happen. Also, Despecialized is going to be pretty close to the same file size, if not slightly smaller (16-20GB). I think revisited is only 480p, designed for a DVD, hence having such a small file size. You could also torrent if you can use that method, to help with the long waiting.
