So its not like it still couldnt be used. thoughts?

DD+ was created specifically for HD DVD since the bit packet structure was limited to the old DVD specs, which could not do 640Kbps. (Blu-ray could handle the different structure...) You should be able to find some notes about it from Roger Dressler in the AVS forum.

Dolby is looking to adapt DD+ for use in HD broadcasts down the line, but since Blu-ray discs generally have either Dolby True HD or DTS MA, there is no real need for DD+.
