I have the Blu-ray set, but my disk 5 (The Work Print) is just a normal DVD, not a Blu-ray disk. This was an error with a few sets. Hope it will make my set worth more money to collectors in the long run. For now, it's just annoying that I will have to buy another set just to get all 5 disks in Blu-ray format.

Both the HDDVD/Blu-ray have discs 2 and 4 as DVD's. Discs 1, 3 and 5 are HDDVD/Blu-ray.

I think the bars are indicative of it being a 70mm print? I'll give my HDDVD disc 5 a look sometime.
