best dvd player for 720p tv image
diggittey
I have a 720p hd tv-but also have a blu ray dvd player, and I know they play at 1080i--just wondering if watching blu ray dvd on a 720p is redundant in that an upconvert can give the same image. Just curious???? I plan on getting a 1080--just waiting to see the 120hz's to come down. thanks.

There is no 'stretching' involved.
It's not making it true HD
What they are doing is basically tons and tons of math. The signal on a DVD is 480 pixels by 720. So a chip in these players is taking that and making it into 1080x1920 i or p or 720p. It comes out as that new higher res signal, but it can't create more detail that what the original contained. It's just a trick, and it's generally better done on a DVD player than in the TV.
It does help things look cleaner and less jagged since you can notice such things more easily on a huge HDTV. But understand, no upconverting player, no matter how expensive or how advanced the chipset, will give you more detail than a true high def, high bit rate source like a blu ray disc.
Not all 720p HDTV have the same res, as there are three different pixel counts depening on the display tech. They are 1024x768, 1280x720 and 768x1365 (give or take) the pixel count runs from about 750k to about 1 million, that's three to 4 times higher pixel count than regular DVD.
So even though you don't have full HD, you'll still get the benefit of the extra def that blu ray offers. The player can be set to 720p or the TV will down convert a 1080i signal (if you set the player to that) note, not all 720p sets can handle or convert a 1080p signal. Not to worry just set the player to another resolution.
Hope this helps, go out and get a blu ray on black friday! Wal mart will have one for 128 rocks, that is if they have any left.

Will a blue ray disc player work well with a 720p lcd tv?

I know that a blue ray disc player is awsome with a 1080p lcd tv. But will it look better than a regular dvd player or upconverter on a 720p tv?
Answer
Absolutely! Why does HDTV look better on a 720p set than watching SDTV? You're coming from a much higher quality source, and the result is a petter picture.
It's pretty much what we has when DVD came out 10 years ago and everyone at that time had regular analog sets. DVD's gave such a better image because of the fact they were a Digital source. Now that's where we are getting at with HD-DVD and Blu-ray
