I know this may be a stupid question and i prob know the answer, but I need to ask just to make sure..

On the Pioneer 640/543/540H's(I have the 540), I accidentally deleted a movie just now that was on the hdd. Is there anyway using the 540 to undelete it? thanks..t

Sorry, no way to undelete.

There is on a DVD with an undo, so you would think they could add this feature to the HDD.
