Yes, there is an auditions disc from OCP (me). It's sourced from a bootleg VHS bought at Comic Con one year.
Nothing fancy, but it's different from Rikter's (slightly better I think) and contains really high quality versions of The Saga Begins and the Richard Pryor Cantina, sourced from official DVDs in both cases.
Some people have it. It's known as OCP's audition remix.
>> Movealong, are there also DL Versions of Episode IV and V from OCP?
No, Star Wars and Empire were created specifically for the single layer format and a dual layer was not attempted.
Actually, a slightly dual layer version of Empire does exist. It's about 5 gigs I think and it's never been released. It might come out when Jedi does. But the extra data is SO slight that there is no visible quality difference whatsoever from the single layer. Which explains why it was never released!
