Why when I copy a DVD do the subtitles now come switched on as default?

I have done a 1:1 copy with a DVD that was less than 4.7, and one that just took the main VOB`s then used IfoEdit to create ifo files.

In both cases, when I play the films on a standalone, the subtitles need to be switched off, rather than switched on.

The orginal disks don`t have this problem
