I keep reading that DVD's can be converted to display 1080p on Blu Ray players is that the case? and if it is why not keep buying DVD's? I started a Blu Ray collection and was planning on selling all my old DVDs but now dont think I should if they are display in 1080p, Thanks for the help

Basically false pixels are used from surrounding items to fill in the space, I am lazy and dont feel like typing so I am gonna link an article

After deinterlacing, the Standard Definition DVD video must then be scaled (or "upconverted") to the higher resolution of the HD display. The standard DVD resolution is 720x480 pixels, or 345,600 pixels in each frame. The 720p HD resolution is 1280x720, and the 1080i HD resolution is 1920x1080. In order to produce an HD video signal suitable to be displayed on an HDTV with the higher resolution and best picture quality, an upconverting DVD player must scale up the video frames.
Scaling involves creating new pixels by selectively copying pieces of the surrounding pixels using various mathematical techniques to interpolate what the video signal would look like at a different resolution. A good upconverting DVD player scales the DVD video using fast processing electronics and intelligent algorithms. It can detect and compensate for motion, scene transitions, foreground and background objects, and noise from video in real time and handle each situation intelligently. The scaled-up video is rich in detail, with little or no visible artifacts introduced by the upconversion process.
There are some upconverting DVD players on the market that cannot do the job well. Perhaps they employ low-quality detail enhancement circuitry to simply enlarge video pixels from the original DVD to fill up the HD screen, or perhaps the electronics and algorithms used to handle the tasks are not adequate. Viewers will notice artifacts such as v isible pixelation, color shifting, jagged lines, and "ringing" borders introduced by the poor upconversion. These artifacts are often mistaken for digital compression flaws in the DVD itself, when in fact the DVD player and/or display may be causing them. The high-quality upconversion performed by a player such as the OPPO OPDV971H makes certain that what you see on screen accurately represents what is really on the disc

A blu-ray is already is scaled to produce a 1080p picture so theres no up scaling involved.

yeh, what he said.

easy, go to a photocopier, now put in a sheet of paper and use the zoom function on it, does it become better or just bigger? you can't add info where there is none. all you can do is try and fake it and get something uglier.

Yeah thanks for the help guys

I wouldn't dump all your old DVDs just yet. BD are a pricey and newer DVDs upscale nicely. I have tons of DVDs and I am replacing my collection a little at a time. For me, there just aren't enough BD titles to justify scrapping my entire DVD collection just yet. Keep in mind that you could be waiting a long time for some of the older more obscure titles to find their way to BD.
In my case I have pretty much stopped buying DVDs an opting to buy all my new movies on BD. This also helps me avoid having to lend my movies to my family member (most of whom do not have BD players ) I have a PS3 40GB that upscales and looks pretty nice on newer DVDs. One good example of how upscaling does fall short though is the old DVD of Blade Runner-The Director's Cut. I have owned this DVD for years and decided to buy the BR-Final Cut on BD and watch them side by side. I was shocked at how crappy the supposed "remastered" version looked compared to the BD version. It was, and I know this is cliche, night and day. Unfortunately, some titles don't seemed to be headed to BD. For instance, I am an X-Phile and own all the seasons on DVD. For X-Philes a BD version of X-files seasons does not appear to be in the cards so I am holding onto my 9 seasons of Collector's Editions.
Just my opinion. Hope it helps.
