Buena Vista has announced some details about their upcoming Blu-ray Disc (BD) movie releases. Disney is releaing Dinosaur, Eight Below, The Great Raid, and Jay and Silent Bob Strike Back on September 19th.

We’ve seen that the quality of MPEG2 BD releases can be subpar, and usually are. We’ve also seen VC1-encoded Blu-ray discs from Warner that look quite spectacular, no different from the HD DVD versions of the same disc. But what about AVC/MPEG4?

We’ll find out soon enough, as two of Disney’s discs will be AVC/MPEG4 encoded - Eight Below and The Great Raid. The other two are still encoded in MPEG2.

Every disc will have a 48kHz/16-bit uncompressed PCM 5.1 surround soundtrack and standard DD 5.1 surround soundtracks. Dinosaur also gets a full 48kHz/24-bit PCM track plus a DTS 5.1 surround option. Why only Dinosaur? Beats me.
