ok I ended up buying the advent 30" widescreen HT3061A TV because I couldnt pass up the deal (I only paid out of my pocket $380) I went out and got a cheap DVD player to tide me over till high def DVD players go down. I put in national treasure to watch in 16:9 and I got the bars across the bottom and top. I found a setting for 16:9 on the dvd player and all that did was make the bars smaller, they did not go away. the TV was also set to16:9. how do I get rid of the bars? will the bars always be there even if its a widescreen TV


also my DVD player says it sends out "500 lines of crystal clear picture" and when Im watching DVDs sometimes when the screen gets dark like if black fades into while on the movie it looks very bad, the colors do not blend evenly at all. my tv is 1080I so does this mean that my dvd player is only using 1/2 of the bars that it could use or is 500 a good number?

You need to read the "Bars, bars, and more bars" topic in the Lounge...

Your player only sends out 480 lines, just like all the rest. On a 1080i TV, it's usually shown as 540p (scaled).

Your TV has an aspect ratio of 16:9 (1.78:1). "National Treasure" has an aspect ratio of 2.35:1. It states this clearly on the case under the heading "Specifications". Consequently it can only fill 75.7% of the height of your screen. The black bars at top and bottom are supposed to be there. The phrase "Enhanced for 16x9 Televisons" that appears after the listed aspect ratio simply means that it is designed to produce a sharper picture on a widescreen TV than on a standard 4x3 TV.

This is explained more fully in the topic identified by RSawdey in his reply.

so you say that my dvd player is only sending out 480 lines. is this why when colors try to fade from say black into white it looks horrable? is there a DVD player that will give me all 1080 lines or something a little better? how can I get rid of this bad picture?

I have never had this problem with any other DVD player or VHS for that matter. why now that I got my HDTV and my progressive scan DVD player do I get the worst picture?

How do you have the DVD player hooked up to the TV?

the DVD player is hooked up using S-video. I assume that S-video is only for video since I get no sound by just using the S-video hookup. I have to use the L and R sound cables to get any sound with S-video

also I did read the topic about bars and to be honest its all a little confusing to me but I think I get it. I just wanted to make sure that it wasnt something wrong with my TV and thats why I was getting the bars.

Im sorry if I sound dumb but I dont know much about HDTVs and all of the stuff that goes along with it. I am trying to learn as much about it as I can.

If your DVD player has component outputs, that would be a better connection. Component outputs will be three connections, red, blue and green.

will that honestly help the picture that much? will it clear up the transition from one color to another?

A component video connection will give you the best picture. You will also probably get the best picture with your DVD player set to progressive scan, if it has that capability.

Composite video and s-video are always 480i, but S-video should still give you a decent picture. You might have a bad s-video cable, but before going out to buy a new one, carefully check the connection instructions in the DVD manual. I had a JVC DVD player that instructed the user to make BOTH a composite video and s-video connection (to the same input) if you wish to use an s-video connection. I tried it and it worked pretty well. But the next day I bought a good component video cable and it gave a noticably better picture.

The cleanest colors come from using component, which keeps all color portions on seperate wires. SVideo mixes Cr + Cb into a C signal, using 2 wires. Composite mixes all 3 together. They need reseperated for use (comb filter) but muddy each other during transmission.

Of these 3, only the Component can carry progressive scan 480p... as well as having the cleanest color.

The short answer on the bars question is that images come in many shapes, and don't all fit the shape of your TV... unused screen must be left blank unless you zoom or distort the image... laws of geometry.
