I have ripped a PAL DVD. Then I used IFOedit to create a template for TMPG to tell TMPG where to create I frames in the output stream(using Force picture type setting in the GOP tab). This enables everything to stay in sync and make the chapter points work. However, I am converting using dvd2avi, avisynth, and TMPG to convert my video from 25fps to 23.97fps. This will make the video slightly longer (but it still has the same # of frames), is it still a good idea to make the TMPG template with IFOEdit or would it even work? If the TMPG encoded file will have the same number of frames as the original, but just be 24/23.976 longer in time, and the IFO template tells which frame numbers to make and I frame, then the template idea should still work. Has anyone tried this? (BTW, the audio will be 5.1 AC3 that I am sretching with Cooledit then re-encoding to 5.1 w/ Softencode).
