One of the things I bought this week was the BD complete collection of "Burst Angel. It's 24 episodes plus extras.

I was curious how many disks it would take to hold it all. It turned out to be 3. So did that mean they shipped me 480p versions of it? Nope, it's 1080p.

The first BD has the first 10 episodes plus three extras. It's 45 gigabytes, so I guess they averaged about 4.5G per ep, which probably is about right for MPEG-2.

The directory structure shows 10 files averaging about 4.5G each, so presumably they put each ep into a separate file.

UPDATE: Interestingly, I can play it in real time directly off the player. No obvious stuttering or pauses, and the highest the CPUs ever get is about 65% busy.

But I can't hear any sound. Dammit. I have got to figure out how to fix that!

I don't see any way around it. I'm going to have to install a player program that knows how to play BD's. I guess I'm going to have to try the newer version of PowerDVD again. Or maybe outright buy the latest version, instead of relying on the free cut-down one I got with the drive.

UPDATE: Here's a thumbnail of a frame grab:

Here's the real thing, full size.

UPDATE: I just took a look at the files using MediaInfo. The video is AVC, which is a version of H.264. That explains why I can play it without stuttering. And that also explains why the files are so small. The Aika Zero file, which did use MPEG-2, was twice the size.

The audio is "AC-3 (TrueHD)". That's a version of Dolby Digital.

The subtitles are in something called "PGS" which seems to be the standard for Blu-Ray for text streams.

They show up in Zoom Player's streams menus, but only as ID #'s. When I tried to select them, I got told they were unrecognizable formats.

I've tossed the whole report from MediaInfo below the fold, for anyone who's curious.
