Hi Acadia.

Drop the .VOB anywhere - any folder anywhere.

Start V6I PLE. Go to File Menu->Load Object. You should get the "Top level" dialogue. At the bottom of that dialogue there's a browse option (next to the waste bin - hover over the icons there). Click the browse option and you should be able to browse to wherever you saved the .vob and load it.

However, I rather think that you won't be able to save it out as eg. a .obj file (tho I hope I'm wrong).  Many .VOB files are set up so that they cannot be re-exported.

However, just in case I'm wrong, to try to do so select the object, and go to File Menu->Export Object. Select .obj format.

Hope that works (I have V5I, not V6I, but I'd be surprised if these bits have been changed)

Cheers,
Diolma
