1/5 DVD a dud!
  by M. Smith (Paynesville, MN)
The DVD did not play on any player in our house. After further review, this is common for MOST DVD's. Why sell a product for DVD players that doesn't even work?!? They do not even have technical support to contact.

4/5 Very HD-Friendly, but Incomplete
  by viper0066
The Adjustments for Color, Sharpness, Brightness and Contrast are all superb and quite-well tailored to HD sets.

It is however missing a Tint adjustment (my set calls Tint a "Hue" adjustment). If Tint/Hue adjustment is on the disc, I haven't found it yet.

4/5 Someone who's actually used the product

Well, this is the 5th review of this product and the first one by someone who has actually used it...go figure.

This product is very similar to design and function of the original Digital Video Essentials (DVE) for standard DVD: it has in-depth explanations of current display technologies and how they differ from each other as well as (the most important thing) video and audio test patterns to setup and calibrate your video and audio system (as well as instructions on how to do so).

The HD test patterns are encoded as VC-1 (video) at 1080p and 720p, and Dolby TrueHD (audio). The basic video test patterns are essentially the same as what can be found on the DVE disc but the advanced patterns are different and include a one-pixel-on-one-pixel-off test for 1080p displays, as well as various shades of gray boxes with PLUGE patterns. (It may be of interest to some that the Toshiba HD-A35 HD-DVD player that I have does not pass below-black information. It does not, however, seem to clip the above-white signals). Through testing, I came to the (somewhat surprising) conclusion that my HD-DVD player and Panasonic standard DVD player require essentially the same settings on the display when using the HDMI cable.

The audio test signals (and my subsequent A/V receiver settings) were very different, however, from standard Dollby Digital 5.1. Because my receiver does not have any HDMI inputs, in order to enjoy 5.1 Dolby TrueHD, I have to utilize the HD-A35's internal decoders and analog audio outputs. Standard DVD's have sounded very different with this setup so I was looking forward to the audio test signals on this disc (particularly subwoofer level adjustments). However, the audio test signals are much more limited in quantity than the DVE disc. It's by no means spartan (and it even has a few additional tests over DVE) but the number of tests is small. There is a dedicated LFE signal to set subwoofer level, but the Full-Bandwidth test for all speakers is mistakenly recorded as Limited Bandwidth (which already appears on the disc) so there is no simple way to match subwoofer level to main speaker levels. There are separate Full-Bandwidth signals for the 2 front speakers (and they indicate that they were recorded at the same level as the LFE signal) so this is what I used. I was hoping there would also be DD+ test signals, but there was only the (superior) Dolby True-HD. Ultimately, I was not left high and dry by the audio test signals, but there could have been more of them to finetune the settings.

Navigation of the disc is fairly simple but because HD-DVD works differently than DVD, you may find yourself over-shooting the test you actually want.

All in all, I think you can probably use your original DVE disc for most video setttings and the audio settings can be done fairly accurately with your HD-DVD player's test tone (if it has this feature). There are additional tests that make the disc worth getting (or if you don't already own DVE, this is a must-have) but it's (few) shortcomings drop it to an overall 4 star rating.

For first time calibration disc users: 5 stars
For owners of the original DVE for DVD: 3 stars

3/5 Not working on XBOX 360 HD-DVD Player
  by woody (Utah)
To my dismay this HD-DVD (as of 31 Mar. 08) is not working with the Xbox 360 HD-DVD player add-on.

I pre-ordered this movie and was anxiously counting down the days until I received it.

I gave it 3 stars because I can't rate the HD-DVD until I use it.

Hopefully there will be an update soon.

I seem to recall reviews from the prior version of this DVD needing an update on the 360 and it eventually was released!

Lets cross our fingers and hope for an update soon.
