I have BenQ 1640 with latest firmware version BSRB (but I have same problem with all previous versions, starting since I bought the drive and installed firmare version BSOB).
Currently I am burning â€œDVD-R TYG02 1-16x SPEEDâ€. When I am burning .iso or .img files on a disk the result seems fine and my external DVD player plays the movie fine.
However when I try to copy the disk I burned, most times I am getting error after 70 â€“ 80%. When I insert the disk in order to copy its contents to my hard disk and then burn them separately, again there is an error “Cyclic Redundancy Check” near the end of the copy procedure.
The only way to overcome the errors seems that is to disable the â€œWOPCâ€ through QSuite version 2.1
Each time I disable WOPC the burning seems slightly faster, the external DVD player plays smoothly the DVD and the copy on the fly works flawlessly as well as the copy disk contents to the hard disk. The problem is that after every system restart the WOPC resets itself to â€œenabledâ€ and many times I forget to disable it.
Do you have any comments/advises on this?
Also the burning of a 4.3GB .iso or .img file from a hard disk to a DVD-R TY02 takes max 6 minutes.
The â€œcopy on the flyâ€ procedure of this disk to an identical disk takes about 12 minutes (double time). Is this normal?
