That *can* be true. But that's like saying that since film is only 24fps
and NTSC TV is 30 fps means that there's *more* image data in TV
programs Also based on the pixels per frame calculation). It's true that
a lot of information gets "tossed" when converting to digital (we live
in an analogue world, right?) but it also depends on the source
material. You also need to take into consideration what is actually
perceptible with the human eye (but that's another discussion). There's
a visceral aspect to 24fps and film (which is why so many digital video
cameras try to emulate it) that they try to preserve in a digital
transfer (the "Holy Grail" :) ). So putting a specific percentage on
this is not really possible since every film, size, frame rate, and
process is unique in its own way, but 95% is way too high.
The 70mm film only makes a small difference when "cleaning" the film
after a digital transfer, not when outputting the film to a DVD-
compatible fileset. (or HD or Blue-Ray, as the case may be). I've heard
this excuse repeated over that last year or two as a reason for
delaying the Hamlet DVD and it's has such a minimal effect over the
process that it's a joke (we're talking about a question of a
week...maybe...). Anybody who works in digital video would laugh at this
repeated excuse that it's been delayed so long for that reason.
Personally, I bought a Panasonic DVD player that does a very good job of
upscaling regular DVDs to HD. More and more players are coming out with
this function since there's such a huge existing base of people that
have large DVD collections. But just like there are films on VHS that
will probably never be transferred to DVD (because of no interest or
cost), there will be movies that will never make it to HD- DVD or Blue-Ray.

A DVD is typically 480x720 pixels per frame. The width can vary, but the
number of scan lines is no more than 480. The High-Definition formats
have up to 1080 scan lines; 1080x1920 being a typical size. Film has
even higher resolution, not measured in scan lines or pixels, but the
clarity of film degrades when projected on imperfect equipment. How
often have we walked into the cinema and seen that the movie is not
quite focused correctly?
On the other, other hand, DVDs (standard and high definition) compress
the image, and the quality of the result depends on the care and quality
of the compression process.

It's difficult to quantify the data density of film stock and it varies
with 'speed' (sensitivity to light), but the effective resolution of an
average 35mm frame is 4-6 million pixels.
A frame of DVD-Video is around 0.35 million pixels, so in the transfer
around 95% of the image is lost. The new high definition equipment
(HDTV, HD-DVD, BluRay) shows 1 to 2 million pixels. Playing your old
DVDs on the new equipment will reveal their shortcomings.

[Editor's Note: Gabriel, the next time you are in the Washington, D.C.,
area, get in touch with me and I will show you how awesome my system is
without (HD-DVD, BluRay) but with my 1080p DLP HDTV. And I still haven't
figured out how to hook up the HDMI connection so that I can still have
the home theater surround sound. -HMC]
