getting pgc's from vob files

[Master of Puppets]

hi, i know this may be a stupid question, but i was wondering if anybody knows how to extract the different pgc's from .vob files i already ripped, i know u can just use dvd decrypter in ifo mode but i borrowed this dvd off my friend and gave it right back after i ripped it and i'm in kind of a hurry to get this off my HD so i don't have time to rip it again... does anybody know how to do this? thanks a bundle

If you ripped the whole disc it is very simple. Load up smartripper and press the eject button after no dvd is found, choose the directory where you ripped the movie. Then choose the angle (PGC) that you desire. Re-Rip and enjoy. I've had limited sucess with main movie vobs also, as long as you have the video_ts files.
