Found and fixed the problem over the week-end when i had some time to spend with it.
With out going into all the steps - my little experiment definitly screwed it up. It was no fault of PVD.
Now I find the pvdconfig.ini file you are refering to -> In Application Data\Portable Video Database folder.
When searching the drive it also picks it up...
And now when i do a restore to the Database - all my images are back in place.
But it did give me a chance to look closer at PVD.
And I found that "Portable Switch" you refered to - the "protable.batch" file
Now we're on the same page on this and i understand better... that and I got a chance to read your Getting Started page in the Help section - the page i was missing explained all very cleary. - figures ;-)
I will say though I found the download that actually says portable - scans better... don't know why but it picked up multi dvd's that the first one didn't and put them under the apporriate eppisodes. Though it didn't include an episode title.
I find the rescan has some issues. but no matter - I pretty happy with it.
Thanx for the help rick and the help page...!
