Hello,

I'm wondering why when you compile just a video stream, a m2v, without any audio or subpictures at all, the resulting VOB is rather bigger than the m2v.

For instance, if I compile a 4000 MB m2v the resulting VOB has 4093 MB.
93 MB are not a few MBs. Anyway I suppose that this difference of size is a normal thing, because the container must always be bigger than the content. But couldn't the people who created the DVD format make a container that would use a little better the space? It's not that easy, I know.

Well, may be someone has a good explanation for all that.

Thanks in advance
