Does it mean that it can turn ordinary DVD movie into high definition video? If so, there is really no need for expensive blue ray discs and player, right?

It basically means that the DVD player is using a mathematical algorithm to upscale the standard DVD resolution which is 720x480i to 720p, 1080i or p. Sadly, it's not turning it into a high definition movie. There is no magic software or hardware that can create or recreate more actual detail than the original material. It's just going to make things look a bit better.

Even with a 'standard' DVD player, your HDTV will up scale the image, if it didn't you'd have a small 720x480 window in the middle of your flat screen TV every time you watched a standard DVD.

If you want to see true high definition images, you need an HD source whether it be HD SAT, cable or blu ray disc. As for the expensive blu ray player and blu ray discs, I'm not sure where you are seeing these high prices. You can get a good blu ray player for less that 100 bucks, and walmart and Target both carry a lot of blu ray discs, some as low as 8 dollars. Walmart even has a nice section of blu rays that are all between 8 and 10 bucks.

I don't buy that many blu ray discs though, I rent them from blockbuster.com, I've also had a good experience with Netflix too. I watch 3 blu rays every weekend, that's about 12 a month, and I pay 16.99 a month, can't beat that. The image quality is the highest with blu ray, HD on cable and SAT is always compressed, it looks better than standard def, but not as good as blu ray.

It basically "MAGNIFIES" the standard def signals to fill 1080. It cannot add information that was not already there.

Note: Your television already does this. Every HDTV has a 'preferred' internal resolution like 720 or 1080. When you feed it a standard def video signal, it will up-convert it to it's internal format.

Do NOT buy a DVD player. Buy a real BluRay player as they are around $100 and they all up-convert, but give you access to real HD video as well.

Up converting a bad signal will also look bad. Most manufacturer have stopped producing stand alone dvd player and producing blu ray disc player, which also plays the dvd. The price of blu ray disc player have dropped alone with most blu ray disc movies. Hope this will help you out.

Well, yes, in a perfect world your DVD would play in full HD and there would be no need for BluRays.

In reality though, at least from my experience, upconverters don't do much. It won't really look like full HD without the BluRay, but it would probably look better than standard definition.
