hmpf I'm not sure m8, I had similar problem when I was trying to watch widescreen movie it would not keep the aspect ration to 16:9 which was same as the source. On the pc it would look fine, but playing on dvd player+TV it just goes all fullscreen with the left and right sides chopped off. Eventually I got it to work, but it was not perfect.
WinAVI and VSO Caused the original Problems.
I then used the tutorial in this forum by chickenman on avi to dvdr in which the main software used was DVD2SVCD with CCE Encoder. Read the tutorial and try it. I too wanted a simple program to do it rather than wasting time, but this is also very easy to use as long as you follow the tutorial.
