First, great piece of software you have. I love how easy it is to specify exactly what you want. However, there is one thing I'm not able to change. I have three videos, all 1280x720 NTSC h264, good quality. I'm adding them to the DVD menu, but they get down-converted to NTSC 720x480, and the video quality becomes, well, degraded. Is there a way to manually change the ffmpeg conversion to retain the original settings? When I select the video, the 'do not remultiplex/transcode' option is not selectable....
