I feel sick over this. Blu-Ray uses conventional MPEG for compression. This explains the drive-me-crazy pixel crawl I’ve seen in just about EVERY damn Blu-Ray demo or for-sale disc. HD-DVD uses an entirely new compression method and its images have all been stunning.
What a reversal from the VCR Wars! Back then, *Sony* had the superior image. This time, it’s their competition that does (or, now, did!).
Mike, you make me laugh! The core technology of both formats is essentially the same. The key difference at the root of this war is the Interactivity platform. Blu-Ray is using a java based platform while HD DVD is going with Microsoft HDi. Both formats are using a violet laser at 405nm to read and write data. The rest of teh war is vicious politics and money (baboonery)
By the way, as for video codecs on both format, they support the same video compression standards: MEPG 2, AVC and VC1. The Movie studios decide on the compression but the format itself supports all.
On specs alone, Blu-Ray offers more. On image quality, there is no difference as both formats are resting on essentially the same technology.
Elo: Blu-Ray has a 60% higher capacity per disk/layer than HD-DVD. This would imply you need to compress your files less to make them fit on the disk leading to higher quality images. Or you can keep the same compression level and get more video hours per disk. This might not be noticeable by the average viewer of a typical 2 hour movie. However, it should make a difference for TV shows which will need less number of disks with Blu-Ray than HD-DVD.

That’s funny, I guess HD-DVD must make you sick too, since H.264 is usually the underlying codec for both formats.
The last I checked though, there were some major DRM differences between the formats, and that HD-DVD had plans to increase disk capacity.
