CDBurnerXP: Burning Error Occurred, disk unusable

Hi experts,
I have a lot of video files from all my vacations and family gatherings I attended. All are saved in my computer.
I am afraid if ever my computer crashes, all this videos will be gone.
So I decided to create a CD backup. I downloaded a copy of CDburnerXP and install at my computer.
After installing it, an error occurred, I pasted below the screen shot.

Burning error occurred
An error occurred while burning the disk. Most likely the disk is not usable.
Usually, these errors happen if the inserted media is not compatible to the drive
or of poor quality.
(devMediumNotPresent_TrayClosed) Error closing session (Session: 4
Medium Not Present – Tray Closed. – 0x023A01
Please help me locate the error, is it with my blank CD, my computer or the CDBurnerXP.
Thanks.
