Movie: Picture: Sound: Extras:
I got all excited for a moment when I looked at the back of the box. There it said 'Enhanced Visual Commentary'. I got excited not because I wanted to necessarily look at the movie's director while he explained what he did, but because I thought this might be another BonusView title I could add to my small collection. I need these to test out Blu-ray players.
But there were limitations on this commentary. In particular, the mighty 7.1 channel DTS-HD Master Audio soundtrack didn't seem to be available. The sound instead was standard DTS at 1,536kbps. So I whacked the disc into my computer and checked what PowerDVD had to say. As far as it was concerned there was no secondary video or audio. So I explored further.
The dual layer disc is large, containing 44.8GB of data. But most of the extensive special extras -- including lots of photos galleries and nearly three hours of high definition featurettes -- are on the second disc. The movie is only 113 minutes long, and VC1 encoded video couldn't seem to use this much data, even with that mighty sound track (this dawdles along at between four and seven megabits per second normally, and peaks over nine during some of the loud bits!) And it doesn't use that much data. Roadshow, in view of the existence of Grace Period Blu-ray players, has actually placed the movie on the disc twice. The regular movie resides in the file named 00004.m2ts which is some 24.1GB in size, while the 'Enhanced Visual Commentary' version is in file 00000.m2ts and comes to 20.0GB (presumably thanks to the reduced audio data load). The other 0.7GB is menus, the Roadshow logo, and such.
