The HD Advisor is a weekly Q-and-A column at highdefdigest.com in which readers can send in questions to which the staff tries to help answer. Anyhow, in this week’s column, they go over why some Blu-ray discs don't support play-resume:
[…] Just to clarify, the lack of a Resume Play option is tied to BD-Java […]. While all BD-Live discs are authored with BD-Java (so they do go hand-in-hand to a certain extent), it’s also possible for discs without BD-Live to share this problem. Java-enabled discs will usually start with a “Loading” icon before the main menu, and tend to take longer to load than non-Java titles. All of Fox Home Entertainment’s James Bond Blu-rays are programmed with BD-Java, even though none have BD-Live content, for example.
I agree that this is a major shortcoming of BD-Java, and I’m flabbergasted that none of the Blu-ray format developers ever gave this issue serious consideration. […]
So, that’s the scoop, apparently; I’m glad it wasn’t just me. (Up until now, I wasn’t quite sure if maybe I just hadn't configured my Blu-ray player quite right.) That aside, though, Blu-ray still offers a phenomenal picture, so I'm going to continue happily buying Blu-ray discs :).
