I’d recommend the setting “Auto Selection”. The “Forced” setting will cause the creation of a new strategy EVERY TIME you do a burn, regardless if an adaption is necessary or not, making you loose a lot of time.
“Auto” is a lot smarter, creating a stratety first and checking susequently if adapting is needed or not. This saves time since adapting is usually needed only occasionally, when the drive detect a change in media quality (a new spindle/box of media may be different).
The “?” Button will give you a short description of how the different modes work.
And yes, a very nice burn! My 760 likes Sony -R too.
