I have been working the last week on trying to figure out how to author a dvd at 23.976fps. Seems most authoring tools only recognize 29.97 NTSC and 25 PAL as standard formats. I really want to avoid converting the audio framrate to 25fps and would much like to keep it at 23.976. I've searched in guides, authoring tools, and more. I'm at a loss. I don't know what the original source was and I do not know how to tell to be honest. Below is a partial list of what I have been doing to date: 1. Extract the .wav from the source video using virtual dub 2. Convert to VCD using tmpgenc using source video and extracted wav 3. Use tmpgenc dvd author Now the above worked when my source was already 25fps and I authored a DVD with MPEG-1 files (I just ignored the GOP length error works fine). I want to do the same with the 23.976 fps sources since most the video I have is 23.976 - I don't care if it's PAL or NTSC format when done, I can play both from my apex. Can anybody offer any assistance or have any tricks to get around this problem?
