IF your question is - does this work? The answer is yes. Does it work well? That's subjective. Remember you're talking about an original source of 480 lines on the standard DVD so it can't be as sharp as a native 1080 line source. If you have a 1080i/p display and the DVD player has a better scaler than your TV it might look better. Or not. Depends.

Does it work? Quite well in fact! The only catch is the player has to have some good scaling, check the player reviews we did...
http://www.hdtvmagazine.com/reviews/rev ... .php?id=20
While progressive plays a role progressive scaling has been in use for quite some time so what is the difference? Oversampling; how many pixels you have to work with and 1080p is more than double 720X480 and that is why SD DVD can look so good with a 1080p display. 720p not so much for the same reason; not enough pixels to work with and 720p on 1080p same problem, not enough pixels.
To cleanly scale 480p and 720p will take at minimum a 2kX4K pixel matrix. They are working on it...

Richard,
Are you saying above that in your professional opinion if I were to get the Panny Plasma 58PZ750U 1080P display then if I was watching an NFL game on Fox which broadcast in 720P that that picture on my 1080P display would not look as good as a SD DVD on the same display????
I just wanted clarification on this. I currently have a Panny Plasma 58PX600U and the NFL games look great on FOX in HD but of course my Display is only 720P and that is what Fox broadcasts in.
I love watching the NFL in HD and would hate to upgrade to 1080P and the PQ on these games is worse.
Thanks for your feedback.

For the science check out the BenQ review
http://www.hdtvmagazine.com/reviews/200 ... jector.php
scroll down to Overscan and look at what happens to 720p. Yep, the errors are really there.
Another article that reinforces what is going on
Waveform 08 FPD/Digital Display Primer
viewtopic.php?t=5479
read the second paragraph about transferring line counts or 1:1 pixel maps from 720p to 1080i and vice versa.
Putting it in perspective... while you do have clean video, great color and more detail than SD the conversion softens detail content. Simply put 720 has the most detail on a 720 display and 1080 has the most detail on a 1080 display. Another aspect of cross conversion is loss of image content due to additional overscan being introduced by the scaler. If you are a nit picky videophile you will pick up on this. For that reason I am keeping my 720p projector along with my new 1080p projector so I can watch both scan rates natively. This is not only for TV but also the PS3 which will output the native scan rate of a game and many are 720p.
If you are into sports the fact of the matter is most of it is captured in 720p and the best reponse will require the broadcaster be 720p as well. There is a lot of destructive cross conversion going on in the background before the feed ever gets sent out so it may be moot. With that said though I have found Boston Legal and American Idol simply have more detail on my 720p displays. On the flip side my local for Smallville changed to the CW and along with that they changed transmission from 1080 to 720 and Smallville has never looked the same since on either display type.

up scaling
I am looking for an up scaler to convert composit video, svga, 480p component etc., to 1080i component. Can anyone post a link to a manufacture or distributer of one. I would like to pay under $200. Many thanks!

I'd like a brand new Porsche 911 for $10K but I don't see it happening, either.
A true scaler like that would cost 3-10 times that much. You can get upconversion of all those sources to component video with an inexpensive A/V receiver for $400 or so but I don't think it will upconvert everything to 1080i.
Why do you need this?

Re: up scaling
The only way you are going to get close to that price point is used... look for 2-4 year old Lumagen and DVDo. New stuff starts at about $1000.jacknoah wrote:I would like to pay under $200. Many thanks!
