Why does DVD2ONE compress less then 4.7GB files?

[vice86]

I'm used to my DVD Decrypter, DVD2ONE and RecordNow Max method...ifoedit looks interesting but looks too complicated after reading some sample uses for it.

What I want to know is that if you rip the .vob files from a dual layer movie and its under the 4.7gb size...why does DVD2ONE make it even smaller instead of just keeping it the same size and just adding the files needed to burn it.

Did you remove any audio streams or subtitles
The DVD2ONE do not compress the file if it is smaller then 4.7 GB,but,if you remove streams of audio the file will be smaller by the size of the removable staf.

Ahhhh yes...i usually just keep the DD5.1 sound and no subs...so thats why its smaller? It's not really reducing the image size, just the fact that im keeping only one audio track and no subs? cool...thanks for the info.
