The firmware within your drive has a list of media that it can recognize and set the correct burning strategy. The drive uses mid codes (manufacturer id codes) that are included on the blank disks. The list of media in the firmware is fixed/static, so that new media coming out after the firmware was published may prove to be problematic for the drive. If it cannot determine what it is trying to burn, the drive may revert to a generic burning strategy, and produce poor burns, or it may simply not burn at all.
This is why it is important to update firmware for dvd burners. Unfortunately, most dvd manufacturers stop putting out new firmware for older drives within a year or two. So we try to recommend media that is well established, burns well, and has good support in firmware of most drives. This is what we mean when we say Verbatim is a safe choice.
Copy and paste always involves right clicking, so don’t know what to tell you on that. Just highlight the text, right click on the text while it is highlighted and click copy. Works for me. Then right click where you want to paste it and you should get that option.
