None of the product descriptions for these LIMITED EDITION Star Wars DVD's I have seen anywhere seem to explain what these disks are Correctly.
For anyone interested, this edition contains 2 DVDs - Disk 1 is the SPECIAL EDITION version of the film. (i.e. The REMAKE with enhanced effects) Disk 2 is the original 1977 Theatrical release of the film.
The set also contains some trailers and a PC demo of Lego Star Wars.
For any Star Wars buff's, these are obviously the DVD's to own, since you get both versions of the film.
Hope this sorts out any confusion!
