Swapping vob/ifo/bup aka title sets?

[bennyboy01]

I would like to simply swap out a title on a DVD without having to relocate the files and re-encode the whole DVD.
In this example, there are just 2 titles

VTS_01
and
VTS_02
and a menu

If I author a different 2 title DVD, may I swap this set of VTS_02 files for the original on the other
both have only three files for title 2 -
VTS_02_0.BUP
VTS_02_0.IFO
VTS_02_0.VOB

They are both basically authored the same way.
May I just swap them out? Or would this possibly create some compatibility or playback issue? I tested and seems ok, but I would like your opinions. - thanks

Are you just replacing the files?

It might not work as expected on all players. Try instead use vobblanker and use the replace function. Click on it for some guides.
