No. HD is natively 16:9. Many BluRay disks will be authored in 1080p,
and will need to be downconverted for most TV's for a few years.

Thanks for the info.
Is it possible to display a HD DVD or Blu-ray image in the "compressed"
mode?
Will it be possible to use the anamorphic lenses made by
RUNCO(CineWide) and
SIM2 with the HD DVD and Blu-Ray players? They seem to rely on the
possibility of
displaying the image from the Projector in the Compressed mode and
letting the lens unsqueeze it rather than the projector's electronics?
Will this be possuble with the new HD players?

Somebody at www.projectorreviews.com indicated that the HD DVDs and
Blu-Ray are encoded at 1280 x 780 rather than 1920x1080. Is this
correct?

I really doubt it. HD formats are all 16:9, and to this point I've
never heard of any sort of anamorphic compression being used. All the
HD titles I have are square pixel -- even the 2.35:1 OAR titles. That
might just be because they're from cable/satellite, but I don't think
so (as I also have several 480p titles that *are* anamorphic).

>Will [using anamorphic lenses] be possuble with the new HD players?

Again, I doubt it. At least not for native HD material. I'd imagine an
anamorphic lens will still be great for DVD-sourced material, though.

I believe encoding at that resolution is possible, but everything I've
read suggests it'll be 1080 on the majority of releases on both
formats.

1280x780? That seems oddball. The two HD formats are 1280x720 (usually
progressive) and 1920x1080 (generally interlaced right now, but
progressive is becoming more common).

The format used on HD/Blu-Ray DVD's may depend on the original source,
too. Most movies will probably be 1080i/p, but some video-based material
(TV shows, sports, etc..) could be 720p if that is the original source
format.

Sorry,my typo, I meant to say 1280x 720.
