Gordon Ho Executive Vice President (worldwide marketing & product management) for Buena Vista Home Entertainment (Disney). Had this to say.

“We believe so and have put our support with Blu-ray at this time and that’s because largely it has the better specifications. It can deliver a better picture because of the bit rate, beyond the fact that the disc has more capacity. So there’s two different discs – Blu-ray and HD-DVD. Blu-ray, the dual layer, holds 50 gigabytes of data. The dual layer HD-DVD holds 30. So when you want the best picture, would you rather have 50 gigabytes of information or 30″?

“So we found this meant Blu-ray had the room for the best picture and sound. The other thing it has is what we call a peak bit rate. What this is is how much data can you send over a pipe in a given second. Blu-ray can send 40Gb of information per second. HD-DVD can only do 29. So when you have an action scene and you have all this information on the screen – you’ve got fire, you’ve got people running about – you need to use so much bit rate. You have all this stuff happening and you suddenly need all this information to be sent through. Blu-ray has less limitations, so that’s another benefit. It has space and it has space in the pipes”
