Does anyone know if this set up will look fine in the end....I have a Sony 720p dvd player that upconverts to 1080i...will this picture look good if I buy a 1080p 50" tv?

What's a 720p DVD player?

HD-quality DVD playback: The ideal addition to any high-def home theater system, the DVP-NS75H features playback at 720p and up-converts to 1080i through the HDMI interface for high-definition pictures that will dazzle you.

Would the 720p or the 1080i display well on a 1080p tv?

Okay, got ya. Just so there's no misunderstanding: your Sony DVD player plays 480i standard DVDs and is capable of scaling them to 720p or 1080i. In other words, your 480i deck is no more a 720p DVD player than it is a 1080i DVD player. Try it w/o scaling (upconverting) at all--that is, letting the TV perform its own automatic scaling of the DVD player's 480p to the TV's 1080p. Then try it at 720p and at 1080i. My guess is that you'll either notice a marginal difference for the better at 1080i, or you won't notice much difference at all. You tell us when you get it. You might want to read the thread below, or is that one the reason for this one?

thanks ED, he had me confused too. 720P is a HD standard along with 1080i and the newer 1080p so why would a player upconvert from one HD standard to another? as Ed put it try it in all the modes and see if you can tell the difference. Not knowing your player, I think you may be able to set it to upconvert to one of the levels if The TV is compatible with it. NOt going to see 1080p on a set that can only produce a 720p pic or the same with a 1080i set. Mine does one or the other 480p or 1080i. so look at what your TV can support and set the DVD player to that level. And let us know what happens.

Okay, that makes sense. And as for the connection, I should use the best the dvd player has...HDMI...even though it also has component. right?
I'll have to see what format the tv has in addition to 1080p. Thanks

I'd use HDMI first; it gives you the option of upconversion, which isn't available via component, and it avoids D/A conversion if you have a digital TV (like your DLP). If the TV accepts, as well as scales to, 1080p (some can only scale to it), it will accept every other consumer format, but it will have to upconvert all of them to 1080p. If the TV has 1:1 pixel mapping, which I doubt, it can show lesser resolutions--like 480p or 720p--at the center of the screen, leaving the rest of it blank, but, for the most part, digital TVs are restricted to showing everything that enters their inputs at their own native resolution.

Okay. I just want things to look good, not distorted...guess the best way is to just play with the settings and see how good it can get. One site talking about it had this in the description so hopefully other formats will work fine with this tv.
"The television has a display resolution of 1920 x 1080. The HDMI and component video inputs will accept 1080p, 1080i, 720p, 480p, and 480i signals and will display them as 1920 x 1080. All other input signals will also be displayed as 1920 x 1080."

That's the $64,000 question--how well the standard formats will look when scaled to a higher native resolution. You might try to find print or web reviews of your model. I can't imagine, however, that your DLP won't perform well if fed a diet of deinterlaced DVDs. It won't be HD, but it will hardly be unwatchable.
