Happen to be a HD DVD earlier adopter? Sorry to hear that. Paramount and Dreamworks wants to help switch your library to the winning side and is offering up a $10 rebate. All the studios ask is that when you buy a Blu-ray title of a disk you currently own, mail in a promo certificate along with the proof of purchase from the original disc’s packaging. 

That’s not all good reader, this offer applies to standard DVDs too. The promo will began with Transformers on September 2nd and will run through December 31, 2009.
