After doing some research is the only difference that the older yellow cover DVD has a booklet? Are the discs exactly the same?

Checking my database, maintained here, yes.

Personally own both versions, and checked them once to verify all extras are the same. Didn't check the transfer or discID, but I believe it is the exact same disc.

if im not mistaken, all those "decades" collections with slipcover dvds are just repackaged disks. new hat is all.
