Hello! I really enjoy your site here and how your reviewers think. Especially Puccio. Anyway, I started collecting DVDs a few months ago and I still have a couple lingering questions.
1. What exactly does anamorphic mean? (the guide on the review page confuses me a bit)
2.What does mastered in High Definition mean? Does it make the picture cleaner?
Any answers would be extremely appreciated

Welcome to the site, Kulguyssj4.
Let's see: Anamorphic. In terms of movie photography, it has to do with the lens used to film a widescreen movie, squeezing the wide image onto a standard 1.37:1 frame, and then using a another lens on the projector to unsqueeze it to its proper widescreen dimensions. They're known as anamorphic lenses.
As far as DVDs are concerned, anamorphic has to do with the process of adding the additional information (scan lines) available on a high-definition television screen to improve the image quality of a widescreen picture. You've probably read on the back of DVD keep cases about a picture being "enhanced for widescreen" or "enhanced for 16x9 televisions"? Same thing as "anamorphic."
High definiton, on the other hand, refers to a higher resolution than is currently provided by common television broadcasts or today's common DVDs, which are limited to no more than 480 horizontal scan lines. The new high-definiton standard allows for up to 1080i lines or 720p lines (interlaced or progressive scan, methods of delivering the image to the screen). In either case, you can see that there are quite a few more pixels involved for a much clearer, sharper, more-detailed picture. Most television networks are already broadcasting in high definition, and high-def DVDs will be available before the end of 2005.
"Ultra high definition" is also in the offing for the more distant future, providing 2000 or more horizontal scan lines; and after that, maybe something up to 5000 lines, which would equal the very best photographic quality of today. Technology move on.
Incidentally, the term "high definition" is also misused a lot, to mean anything a manufacturer wants you to buy. Be careful.

1) Explaining what anamorphic means would take up a lot of time and space. Suffice it to know that when you get a movie or a TV show with an aspect ratio greater than 1.33:1, you want anamorphic enhancement to take advantage of the new 16:9 TV sets being sold.
2) "Mastered in High Definition" means that a film element was transferred to video at either 720p or 1080i lines of resolution. For current DVD technology, that High-Def master is further downconverted to 480i/480p.

Funny...John's explanation of anamorphic didn't take much time and space at all...:D.
His explanation of High Definition was pretty clear too.
