Old videos into Picture Motion Browser??

Perhaps a dumb question - but can anyone guide me on making all of my old videos (stored as .wmv files) accessible through Picture Motion Browser (installed with my new SR290)? Would love to have them all viewable in the calendar view.

Can't seem to find out how to do this in the Help section.

All guidance appreciated.

Click "tools", "settings", "viewed Folders",

Then "add" Folder Where Your Old Files Are.

Then You Can "update Database" In The Tools
