It seems that the most practical way of making an HD DVD at the present time is to use high compression formats like DivX and burn to a conventional DVD. This can then be played in certain DivX capable DVD players.
Whilst John has an excellent tutorial on the subject, I'm sure that he would admit that the process is more complex, with potentially many more pitfalls than the regular MiniDV to DVD workflow. Although he describes editing HD as "smooth" on his old P4, he would also no doubt admit that hardware issues become more critical with HD editing. This forum illustrates how many problems arise with just the "simple" MiniDV workflow!
Blue Ray and HD DVD players are still way too expensive, and one or other format will surely win out and become the standard, in the same way that VHS overcame the (some say technically superior) Betacam.
Consider the situation if you wish to play a commercial, copy protected HD DVD on your pc. You'll need an HDCP enabled video card and an HDCP enabled monitor. If you want to play the disk to a TV, the TV will have to be HDCP enabled too. In the recent Black Friday sales, people rushed to buy "bargain" non-HDCP compliant 720p TV's, some probably believing that they were getting "real" HD.
In my case, I know that there's more room for improvement in my videography skills than there is in the resolution of my final output.
I for one will stick with Super8 for the time being.
