VOB different size than combined .mpv & .mpa?

vbimport

#1

Why is it that the .VOB that is created by my authoring sotware is larger than the total sizes of the .mpa and .mpv?


#2

stream data (extra info) is added during muxing


#3

what is included in the stream data, or extra info?

The primary reason I’m curious is because I’m wondering if there’s a way I can calculate what the total size of the .VOB will be BEFORE i begin encoding the ORIGINAL content into MPEG-2
