My original download time was 1:47:45,after dvd flick was finished encoding and burning the disk time came out short at 1:39:40,i have tried three different downloads and two different movies and have the same result,what can i do to correct the problem.
Frames Per Second. Usually PAL movies are a bit shorter, so in your case if you were to convert from PAL to NTSC, it would maybe come out a bit longer, not the opposite.
If you play the video with VLC for example, go to Tools->Codec Information-.Codec Details and it will show the frame rate.
