Q: Updated and factory reset macbookpro, how to recover lost videos from the application "front row"

What do you mean you factory reset it?

If you erased & reinstalled the OS then I'm afraid to tell you that those items are gone.

A data recovery company may be able to recover files but it could be difficult or impossible depending on the disk type & how it was setup.

You need to avoid writing any new data to a disk that will be recovered from to stand the best chance of finding deleted files. Power off the Mac & leave it off until you have decided on a course of action.

Don't you have any backups at all?

There is no Front Row with Mavericks, but Front Row does not store anything itself, merely links to whatever is in your Movies folder or iTunes library, so your files should still be there.
