I am no expert on this, but I hope I can shed some light. There is a line inserted into the Avisynth file (that you can edit out, but I don't know the consequences of doing this) that says: assumefps(23.976) for NTSC and (25) for pal. Also the encoders (audio and video) are setup for standard framerates. Since the goal of this program is to make the video work on a TV it must have the proper framrate or will look horrible. I honestly don't think you can make a non standard framerate video with DVD2SVCD. Mark
