HP 300I dvd+R/W

Has anyone used this drive to backup any movie DVD’s.
I have tried dvd xcopy xpress and clone dvd along with any dvd and can’t get any of them to work.

The dvd burns down to about 80 or 80 % then closes and the DVD will not play on the burner or any dvd player.

Does anyone know how to solve this problem?

I am useing HP Pavilion 7975 intel 4 2 GZ
IE 6 sp1
540 Ram

The burner program that comes with the HP 300i is Record Now.
