Pioneer 104

I am able to burn CDs without a problem but when i go to try burning DVDs i get an error after the lead-in and it terminates. I have tried multiple programs and it was working fine for many weeks and has worked fine with this same media. Its not even a new batch. The error i get is not consistent but it always terminates at the same stage. Any thoughts on how a CD can be burned with no problem but a DVD cannot?
thanks

Use good and recommended DVD-R and DVD-RW.
Preferably discs rated at not higher than 4x and if you do so make sure your drive has AT LEAST firmware 1.40.

what do you mean firmware 1.40?

Probably meant 1.04
