Here is a link to an interview about David Mallet discussing the new format Blu-Ray Discs. My only disapointment is that they are only talking about this format for film and not for the music industry to adopt where they could release both the audio recordings and film related features that would correspond to each l.p. release and whatever other unreleased features. link
I'm just waiting for SelectaVision to make a comeback. link
I'd never even heard of these things until we bought a Queen Greatest Flix CED off of ebay.
