Gary,
The Toshiba / RCA HD DVD Set-top Players (as well as the Macintosh with the
right software installed) make do distinction between a blue or a red laser
disk. If a disk has the right format (UDF 1.5 and above) and the right
contents (the correct folder and directory structure), then the disk and all
of its' glorious content will play properly.
Therefore, the author needs to do two things to make an HD DVD. The first is
to construct a disk with all of the proper content so that menus, tracks,
sound, etc. will be properly coded. The second is that a DVD has to be
burned with the proper UDF format. Both of these steps require very
inexpensive and readily available software. I have been doing this for
almost a year, in fact.
The disks are limited in how much they will contain, since the red laser
DVDs and burners we have been using in home computers since 2001 can only
hold a small fraction of the blue laser capacity. Thus the disk you make
will hold either 23 or 46 minutes of total play time depending on whether
you use single or double layer blanks. For home movies this is (in my
opinion) a blessing in disguise, since most home movies are just not worth
watching more than 46 minutes..........!!
The content I am describing is HDV 25 MBit/sec MPEG2 encoded material. It is
indistinguishable from the original HDV tape played back directly from the
camcorder (unless you have the bad taste / bad sense to do multiple
re-encodings during the editing and authoring stage). If you decide you want
to take your HDV content and do all sorts of transitions, filters, heavy
editing. etc., then the final edited HDV may look softer and noisier. This
is also true of standard def DV video, and good editors and authors know how
to avoid this type of degradation.
My point is that you can record HDV on a camcorder, do editing and other
effects (in moderation), write a 46 minute HD DVD, and play it on your
Toshiba. I do it all the time.
