Bitsetting question

I was wondering where i can find a list of dual layer dvd-burners that come with bitsetting straight out of the box. Thanks

That’w maybe possible but don’t know if such a list is available in an extensive format.
Best way it is to choose the burners by their specs and check if they support the kind of bisetting you’re after - either from factory or via a modified firmware.
At the end - and unless you do it in a definitive way - the proccess should be performed by the burning software.
You can also go to the hardware section of the forum and check the subsection of the models discussed there for the bitsetting issue.
