Just bought a new wide-screen high-def TV (and a high-def DVD player), and I find that a good number of DVDs that I have burned from AVI files converted to MPEG2 do not fill the screen on the TV.
The pictures of which I speak are wide-screen pictures, but they float right smack dab in the middle of the TV screen, and there is black on all four sides of the picture. Since the black the same all the way around, it seems that the pictures are the same aspect ratio as the screen. (If they are not exactly the same, then they are only a hair different.) So why don't they fill the screen?
Store-bought discs seem to be OK. The ones I've tried so far don't fill the screen on all four sides; there is still black on top & bottom, but I figure that's because the aspect ratio of that particular DVD is not exactly 16:9 (like the TV).
Could this be as simple as missing a setting somewhere on the new TV or DVD player? If it's the DVDs, is there a way to fix this on future DVDs? Is it a matter of changing the height and width during the conversion process? Right now, I make them all 720x480. Will making them higher & wider, keeping the same proportions, do it?
Suggestions? And did I explain the problem well enough?

Because you resized and encoded for 4:3 rather than 16:9.

It's because your DVDs are 4:3 Letterboxed. The solution is simply changing the aspect ratio setting on your TV. The TV should have at least 3 settings though what they are called vary by manufacturer. (4:3, Standard, Normal...) (16:9, Wide, Full...) and (Zoom, Stretch...) Zoom would be the right setting for letterboxed videos but not all TVs have that setting, personally if it doesn't I'd get a different TV. You may find some older commercial DVDs will have the same problem and some broadcasts, all widescreen VHS & VCDs... The DVD player should always be set to 16:9 when connected to a widescreen TV. For future discs you don't change the resolution, you set the aspect ratio to 16x9 so you'll be making an anamorphic DVD.

Bondiablo, thanks for your reply and for your illustration. The picture labeled '1:1' is exactly what I'm talking about. But I thought that I had used the 16:9 setting when I did the conversion.
In the future, rather than eyeballing the AVI file that I'm about to convert, should I maybe check it with G-Spot, and then use a setting that matches whatever it says? For instance, if the image looks like widescreen, but G-Spot says that it is 4:3, then I should use the 4:3 setting when I do the conversion, correct? I'll explore that and see what happens with some of the stuff I've got waiting on my hard drive.
About using the aspect ration setting on the TV: There is one, with a choice of 4:3, 16:9, or Set By Program. Choosing the 4:3 setting does make the image fill the screen more, but it also squashes it in at the sides so the actors are taller and thinner. Using the 16:9 setting makes the image smaller, but keeps the correct proportions. -

Here is how a DVD should look at the different settings on most widescreen TVs. I don't know what program you use to make your DVDs so I can't say what settings you need. I use TMPGEnc and with it the important settings to make an anamorphic DVD from an AVI are, on the Video tab set Aspect Ratio to 16x9 and on the Advanced tab usually set Source Aspect to 1:1 and Arrange Method to Full Screen Keep Aspect Ratio but those 2 can vary depending on your source file.
