How can I create multiple discs of the same video without regenerating each time?
Select “Generate new video” in the “BURN” panel to generate just the files for the video disc. The files will be stored in the output folder specified near the bottom of the window. To burn the created image file, simply load the previously generated disc image using “Burn existing video into CD”, and set the video folder accordingly. You can also use a 3rd party burner that supports the BIN/CUE format (for VCDs/SVCDs) or the DVD VIDEO_TS and AUDIO_TS subfolders.
