It's an easy fix really, and this is often the fix for many video camcorders out there, and even some electronics devices. All you have to do is reset the camcorder. To do this you need:

Your Flip Mino Camcorder and a paperclip.

Bend the paperclip so the end is sticking out like an antenna. Then, there is a little hole on the bottom of your camcorder. Put the paper clip in there for 10 seconds and remove. Repeat two more times.
