Ubuntu-Rescue-Remix

I would like to retrieve recorded videos to DVD hard disk. I have it connected via USB but in '/ media' does not appear.

In 'Disk Utility' appears:

Is it possible to retrieve the recorded videos using Ubuntu-Rescue-Remix?

I don't have enough

I don't have enough information to work with.

How were the videos recorded onto the disk? What was used to do it?
