Anyone ever download a movie from iTunes music store in HD? What's the quality like? Bitrate? Do they do 5/7.1?
The average bitrate of an iTunes HD download is around 4Mbps and are 720p. Some have 5.1 encoded Dolby Digital (AC-3) tracks, but getting to work can be frustrating.
In contrast, most Blu-ray movies are 40Mbps average bitrate at 1080p and have lossless audio tracks.
As stated before, Apple's resistance to Blu-ray is merely in defense of the iTunes store. From a business standpoint, it makes sense to their bottom line. As much as it sucks, I don't see this changing soon.
