I have an MPEG2 video file.

I burn a SVCD with no chapters: if I rip off the mpeg video file I get exactly the same file (binary compare) I had.

On the contrary if I burn the SVCD adding chapters, when I rip off the mpeg video file, I don't get exactly the same file (although it has the same size).

I believed that I should always get exactly the original mpeg files, no matters if I added chapters or not.

Where did I go wrong?
