I am using the mainconcept encoder 1.4.1. I have an mpg svcd file that is in pal. I open it in virtualdub and use vdub to change the framerate for ntsc. I then start the frameserver and open the main encoder. It reads all of the file information okay but in the preview the screen is green. I have had this happen before with xvid codecs and xvid avi's. I have never had it happen on an svcd mpeg file. Any ideas how to fix it?
