The new version supports 'Menu Extras' on VIDEO_TS.xxx aswell.
(But take care, I did not test it yet myself).
So open VIDEO_TS.IFO, and press'Menu Extras'.
Check the option 'Strip VOB-ID's' and specifiy a destination directory.
After pressing 'OK', you can select which VOB-ID's you want to KEEP!
Uncheck all VOB-ID's you want to strip, and lets rock'n roll.
