How can I fully regain time on a Flip Mino HD video camera ?

-I have saved all my videos to my computer. My Time Left: Is ; 0min 00sec. I still have all my videos on my mino HD. Im also afraid that if I delete my videos from my camera to regain all the original time .... that when I plug my camera into my computer all the videos will be gone. So, what can I do to regain all of my original time ?



PLEASE HELP !
