Burning a video to DVD that will default to opening at actual size.

Hi. I am burning a widescreen (16:9) SD video to dvd using DVD Studio Pro 4. The video has been exported from FCP6 using compressor. The quality is fine and the aspect ratio has been retained for viewing (letterboxed) on a 4:3 CRT and also on a widescreen display. Is there any way, through encoding, that I can force the video, by default, to open at actual size on a widescreen computer display rather than full screen? I realize that the viewer can exit from fullscreen mode and select "actual size" in DVD Player, but if possible, I would like the video to begin playing at actual size without any adjustments having to be made. My concern is that some viewers will not bother to exit fullscreen mode and will view the video at a size not supported by its resolution. It's a video of a photographer's stills and at a display size larger than actual size, the sharpness of the images is compromised. Any way to get around this other than adding some text advising the viewer to watch the video at actual size or redoing the whole thing in HD?
