I am using TMPGEnc Plus 2.521. I am doing a trial run right now.
My source is 1:1 (VGA). I kept on trying different combinations and using preview to see the results. Even though my source if 1:1 (VGA), I set it to 16:9 and left my encoding aspect ratio at 4:3. When I checked the preview, it was displaying like a widescreen; but its not guarantee yet. I have a fear the left & right still might be cut off, so I'll wait until I burn it & try it to claim success.

Didnt work. The sides of the "widescreen" were still cut off cause of overscanning. Now, I am going to try 2.11:1 to 16:9. This way, I can set my DVD Player to play 16:9, and I've checked TMPGEnc's preview. It's supposed to be widescreen. Let you know if it works.

After numerous trial runs, I think I got it, though the solution has nothing to do with the previous trials. It's not perfect because TMPGEnc doesnt perfectly center the picture, but you can hardly notice it. Set all the correct Aspect Ratio settings. Under the Advanced Tab, for Video Arrange Method, select Center (custom size). Remember that it is going to center the video based on the RESOLUTION THAT YOU ARE ENCODING. For the Custom Size, take 12.5% off of the horizontal resolution you are encoding. Now, remeber that you want your final viewing ratio to be the same as 720:480. So, for the vertical resolution, you'll have to do some math. 720 divided by your ENCODING HORIZONTAL RESOLUTION. Multiply the result by your CUSTOM SIZE HORIZONTAL RESOLUTION. Take the result and divide it by 1.5. This should be your Custom Size Vertical Resolution. I know that's probably complicated. Let me give you an example. If you are encoding to half D1 (352x480), take 12.5% off of 352 (308), and that is your Custom Size Horizontal Resolution. Now, take 720 and divide it by 352. You should get 2.0454545... Now, take this and muliply it by 308. You get 630. Divide this by 1.5. You should get 420. This is your Custom Size Vertical Resolution. So, for 352x480, you need to do 308x420. This will give you the closest to widescreen that anything can if your source was not widescreen to begin with.

[aamir12345678]

Sorry for the unnecessary complication. From D1 (720x480), you are shooting for a Center Custom Size of 630x420. However, when you encode to a lesser resolution, like 352x240, then your Center Custom Size will have to be 308x210. This worked well on my TV, but you might see different results, so try it out if you want to force widescreen. If someone knows a better way using TMPGEnc, BY ALL MEANS, PLEASE.

[aamir12345678]

Your TV Overscan might be different. Some trial & error will be required to determine what % you should substract from the encoding resolution to make the Center Custom Size resolution. Sorry again for all that confusion above.

i wouldn't advise people to do any adjustment for overscan. first there's a chance you'll muck up the calculation and get a ditorted image, second, when you get a new tv the overscan may be less, thirdly when you get a digital display like a plasma or LCD you'll -definitely- have big borders round your picture. not good.....

Even in a movie theatre the image is slightly cut off on all four sides so as to get nice "clean" borders so yeah a TV might cut just a wee bit more off but it ain't the end of the world.

Also I tried to follow your math and got lost at some point but I'm not sure you've got it just right.

Thx , aamir !!

Try 2.11:1 , and Full Screen (keep aspect Ratio) ......

[aamir12345678]

What do you mean by try 2.11:1? What were your settings? When I do Full Screen (Keep Aspect Ratio) and the methods I tried earlier in these posts, Even though it has the widescreen look, it still cuts off some of the edges. What good will that do me? If the edges are going to be cut off no matter what, why not just do full screen completely. I am trying to find out like you if there is a "clean" way to produce WideScreen from a Full Screen source. The Center Custom Size doesn't perfectly center the output. That makes me mad. It looks centered on TMPGEnc, but is off center slightly to the left on the TV Screen. It's kind of "bootleg." There's got to be a way! I hope........

Can anyone shed some light on this subject?
