Yes, an up-converting DVD player can be setup to produce 1080i, BUT your 720p HDTV is just going to down-scale to its native resolution of 720p. Why do you want to do this? Setting up your up-converting DVD player to your TV's native resolution of 720p will always produce the best picture quality!

If my dvd player has progressive scan do I need a 720p or 480p TV?

If I don't need it should I opt for it anyway? I've narrowed my TV selection down to two TV's about 500$ each. One is not a big brand name but is 720p. One is a Samsung and is 4 inches bigger but not LCD. Both are flat screen and both are widescreen. Both are HDTV's. What should I do? Also the no name is a flat panel and the Samsung is a SlimFit tube and 16" deep.

First of all, to answer the original question, a progressive scan DVD player runs at 480p (if you're using the progressive scan feature). That's what the "p" in 480p actually stands for. Normal tv's and dvd players scan, or refresh, the image on the screen every other line at the time, meaning that it will change lines 1,3,5,7,9, etc., then go and change lines 2,4,6,8,10, etc. before going back to the odd lines. This is done very fast, so it's not really perceptible. A progressive scan dvd player in our example would change lines 1-10 every time, theoretically giving a clearer, cleaner picture. However, this will not work on a standard tv. It requires either an EDTV (480P) or HDTV (720p, 1080i, 1080p). The difference between progressive scan and non-progressive scan isn't all that great.
Now, for the tv part of your question, one major clarification is needed. 480p is NOT an HDTV, no matter what the box or the salesperson tells you. To be an HDTV, a tv must be 720p, 1080i, or 1080p. The "i" in 1080i is referring to interlaced lines (the even versus odd lines as above). So right there, the capability of the no-name tv is higher. As far as which is better, that is hard to say, without seeing the televisions. If the tv is a flat panel (and not just flat screen), meaning that it is only a couple inches thick, it is either an LCD tv (should have a plastic-type screen) or plasma (glass screen, and if you look closely you can see the red, green, and blue phospors, just like on a tube tv. I would probably be inclined to go with the no-name HDTV flat panel, but you should be aware that you may be sacrificing quality and durability for HDTV capability.
Hope this helps!
