I am tring to encode a movie to DIVX. THe movie has a frame rate of 23.976 which I verified through DVD2AVI yet when I use DVDx 2.0 under input settings and select 23.976 as the frame rate I get an error message saying that the input and output frame rate are not equal and a roll down(up) will be performed. This makes no sense whatsoever. Please help. I am running win XP as my operating system.
