Sorry to post this here, but I don't post in the Blu section.
Does Harry Potter 5 on Blu-Ray feature a progress bar? I remember reading that Blu-Ray discs don't have that feature. However, that was awhile ago. I would think you would have it by now.
It's an obscenely pointless feature since most of us like the progress bar of our player just fine, but FYI, I'm pretty sure the latest menus Disney is using has the Java code to hijacks the progress bar for their own custom display similar to what Warner does on their HD DVDs.
