Lo and behold!
I manged to locate a simple HD-DVD tutorial video that seems to cover the more commercial features surrounding HD-DVD and their usage.
It is interesting to see, plus there are a number of cool Warner Bros. movies in the video clip. Stuff like Batman, Troy, Perfect Storm, etc...
You should check out the clips for yourself and see what you think. Does having this extra knowledge change your opinion of HD-DVD? What format are you leaning towards now??
There are three quality choices for the video and three video formats for you to choose from. Enjoy!
