Nero vision

Hello, i'm using Nero vision 7 to make my own DVD
http://www.dvd-guides.com/content/view/125/59/
the problem is the screen has been cut off at four sides, not showing full screen on my TV, what extra steps i need to take in order to have a full screen DVD?

Search for Overscan and Subtitles.

here is my screenshot of my video information

i have searched for Overscan i know the most used solution is that i need to adjust my resolution
can someone direct me to the link where it guides how to to that, the more better
if you adjust your resolution, how can you know how wide the boders should be in order to fit my TV screen perfectlly?
btw:i'm using Nero vision 7

Resizing alone won't fix the problem. You have to add black borders around the edge so that the black borders fall in the overscan area, not the picture. You can use FitCD to calculate some common values for the black borders.

For a 640x480 divx file you will probably want to resize to about 656x448 and pad the edges out to 720x480. You can use AVISynth, VirtualDub, etc to accomplish this. I don't know if Nero Vision supports the operations.

You can't fit your TV screen "perfectly". The amount of overscan and position of the picture moves around as the TV warms up and cools off. Your TV probably doesn't have perfect linearity either. The sides of the picture probably bow in or out, the top and bottom edges probably aren't perfectly horizontal, etc. Overscan was developed to help hide all those types of problems which are common to CRT based TVs.

No matter what you do you will end up losing a little of the picture or seeing a little black border at some edges. And if you watch the video on another TV in the future the results will be different.

so, after you load the avs file (using FitCD to write the script) in Virtualdub, how can you add the border? or is that it?
if that's it, that means i need to follow the steps bellow:
-use FitCD to write the script
-open the avs file in Virtual dub
-File-->save as AVi
is it right?
any compression?
will this process decrease my video quality?
btw:i heard that you can use tmpgen to do that to, which one you think is better?

Hoping that it'll help... I've included both NTSC & PAL, though I assume at 25 fps you're PAL.

You've got a couple of issues to deal with.
1) The video you have has already been resized to look on your PC like the picture you see on your TV.
2) You're going to loose some quality no matter what converting to mpg2 for DVD.

If NTSC, to get just the aspect ratio back since the video has already been cropped, resizing to 720 width would be the quickest fix. A stand-alone DVD player will automatically shrink the width so you'd see something pretty close to what you see now on your PC, except the edges would be hidden by the frame surrounding the picture tube, assuming you have a TV with crt.

TO get more accurate, if you were to work backwards from the original 720 x 480, you'd get a square pixel frame which would then be width cropped to 640 x 480, so you've lost some of the picture. 640 / .9091 (aspect) = 704 (cropped vid), which is a legal input for DVD, so you could resize to that. Or you could add a black frame either in TMPGEnc or V/Dub resize filter (using letterbox options) to make up the difference between 704 & 720.

For PAL a DVD player would expand the width rather then shrink it (as with NTSC), and you can resize to 720 x 576 (std DV) -- 640 x 480 resizes to 768 x 576 (square pixel PAL) maintaining aspect, & then is shrunk to 720 x 576 for DVD.

So assuming you had PAL video going on a PAL DVD, you'd resize to 720 x 576, probably at the encoding stage as this might give you less of a quality hit.
