I have tried burnding a verbatim dvd-r with every single firmware out there. It alwasy got stuck and would never work.
I’m not sure if it’s the verbatim brand or not but it shouldn’t be since verbatim dvd+r’s work.
I read that upgrading the 851’s firmware to the 812’s firmware will maybe fix this problem. I am scared of doing this since they are different models are there alot of risks in changing models firmware?
