XBOX 360 HD DVD owners....

Are those of you who have purchased this add on blown away by the picture quality difference for movies or is it just a minimal difference and not worth the purchase?

Only you can make that decision to be honest.  You will get a ton of people that will tell you its not worth it (most of them dont own the add-on).  I have it and it is a huge difference but it depends on the rest of your system. 

I have a 56" Samsung 1080P DLP television so for me its a HUGE difference and totally worth it, especially after getting the Elite I am finally 1080P.
