Disc review:

UltimateAVmag.com: Joe Kane Productions Digital Video Essentials: HD Basics Setup Disc

The reviewer is pretty down on the BD version.

The HD DVD version is clearly superior, not only for its My Favorites function, but also for its speedier menu response, predictable display of text, 5.1 and 6.1 Dolby TrueHD soundtracks, and reliable performance with the 720p demo material. For those who already have an HD DVD player or can still get one, I recommend this version of HD Basics over Blu-ray.

On the other hand, the Blu-ray version can be very effective for evaluating current and future players as well as displays, so don't count it out. Also, player firmware updates can often reduce problems with the Blu-ray version—though they can also be a step backward. For example, Kane has identified one player that handled 720p correctly before a firmware update, but not after.
