I convert my project on ULEAD to NTSC DVD 4:3 720x480..etc.. and then proceed with VSO.. and selected the options of 4:3 and NTSC.. when i play the dvd on my xbox it seems it streches the image..width and length.. i also play it on another DVD player the same happened.. on the computer it plays ok..

Can any body help.. i also try to convert it to VOB on the TMPGENC DVd Author..but same thing happened..!

What do you mean "it streches the image..width and length"? There is no such thing as "length" in video, unless you're working with 3D graphics. Do you mean width and height? What version of ULead are you using? What does "...etc.." mean? You can't be vague if want any help.

The player on your computer is automatically adjusting the format ratio to fit the monitor screen but the software in your xbox and DVD player don't have the smarts to compensate for your munged-up "project"... Why dont you just do the whole project with Ulead? I capture, edit, convert and burn with one ULead program (v10) with 100% success. My DVDs play on everything just fine.
