the option opc is recommended?there is a option for set by default the data on the labels of dvd that i will burn?is recommended finalize the dvd? for example if i burn divx?
From ImgBurn forum:
Performing Optimum Power Calibration (OPC ) is a special technique used in newer CD/DVD recordable drives to perform a test write and read in an area inside of the lead-in, in order to determine the best laser power for recording and to adjust to each recordable disc, which may vary slightly from different manufacturers, or for other reasons.
I don't know about the other questions.
Is there a logical reason not to finalize a DVD??
Every time you burn a disc, it is finalized anyway. Only in multisession mode the disc is not finalized if I'm not wrong, but using multisession with DVDs is not a good idea because it fails very often
Multisession works very good for CDs however
