I have many video clips (mostly TV captures) that are 320x240 but this seems to be a non-standard resolution for authoring dvds. I see that I should start out with 352x240? How do I get that extra width without distorting the picture? Can I add blank space to the sides of the video somehow? Many thanks!
Some programs have options whether and how to adjust to fit screen, others let you fine tune the resolution yourself. In any case, most, if not all burning programs have methods to deal with this problem.
