I am looking at getting the LG 37" 720p model 37LC7D, I'm space constrained so that's what will fit in my armoire.

I have a Sony 300 disc DVD changer (DVP-CX870, circa 2001) I don't want to scrap, it has component hookups but no up-conversion, so I'm looking at either a new Sony single disc (DVP-NS75H) or another multi-disc (DVP-CX995V.)

With the 37" screen and 720p will I:

1. see much improvement with the up-conversion?

2. if I do get the new player with up-conversion, will I see much improvement using HDMI over component video cables?

These may be neophyte questions but I want a better idea before I jump off the deep-end. I was at Circuit City and saw a difference between the two, but that was on a Vizio 50" plasma, not the set I am looking at

Upconversion usually makes the picture look worse as the scalers in the DVD player are often worse than the scaler in your TV.

Unless you dish out hundreds or thousands of dollars for an external scaler to match your TV's native resolution, you're just best to output the disc's native resolution.

Even if you were to get a new player, I'd still reccomend outputting 480i over component.
LET'S GO BUFFALO!!!

If it's a no name cheap DVD player I would agree. Good DVD players can have excellent Up-Conversion. Don't know about Sony players he mentions, but Denon does a good job.

I disagree with this entirely... see below for why.

Even if you were to get a new player, I'd still reccomend
outputting 480i over component.

I'd recommend using the progressive setting on your DVD player, which will then do 480p. This will look great compared to 480i. Try any DVD player at a store hooked up to a TV, and go in and out of progressive mode while watching a movie. (The disc is by its very nature interlaced, so matching the TV to the DVD will not produce the optimum picture, as you'll get that in progressive mode.)

I have done tests on a display using HD and Blu-Ray players. Players putting out HD signals (720p, 1080i, 1080p) did not look different over short lengths of Component Video Cable, or HDMI cable. The set I used was not a production model, and did have good A/D Converters. Some cheaper sets might skimp there, and give better results using HDMI.

The real reason to use HDMI, is when viewing HD and Blu-Ray content. There's no problem with the movies being released presently, as the content protection is not been enabled on any disks to date. But when disks start being produced with the content protection enabled, the full resolution will not be available without using the HDMI connector.

For purposes of legacy DVD's, HDMI is not needed, and little if any difference will be discernable between HDMI or component video connections.

it's easy enough to test if the de-interlacing function on your DVD player does a better job than your TV and vice a versa. Pick a movie and don't set your DVD player to progressive mode, let the TV do the de-interlacing and watch. The set the player to progressive mode and watch again.

I agree totally with bcf1963 with regard to de-interlacing and an interlaced video vs a de-interlaced video. I would add IMHO that while Denon makes excellent mid range players, a lot of what you're paying for is their top notch audio features. Again, IMHO, I would readily recommend one of Oppo's unscaling players. Oppo uses Faroudla DCDi like Denon (not same chip) and their new 981HD upconverts to 1080p at a price of $229!

I recently purchased the LG 37LC2D television and hooked it up to the component inputs on my standard (non upconverting) Pioneer DVD player.

Personally - I think the picture is great compared to our S-Video DVD connection on our tube TV.

Nothing quite compares to the HD OTA picture, but we're happy

i would also agree with bcf1963. i am confident in stating my TV has about the best internal scalers available, yet i find an improvment in PQ when upscaling to 720p with the Elite DVD player in my sig(dv46av - [Link: pioneerelectronics.com] ). i have compared all the resolutions, and i like 720p the best.

my last DVD upconversion unit was made by LG and i used it on my Hitachi LCD RPTV. i found this also improved PQ but i found it best set to 1080i. which is strange as the tv native res was 720p. i'm thinking the LG unit just did a better job of scaling to 1080i instead of 720p, and the TV's scalers were terrible.

i havent compared compnmt vs hdmi, so cant comment on that as the LG was hooked via DVI, and i now use HDMI for the Elite.
