Should I read at lower speeds?

[Machina]

I checked all my background services, and startup - nothing new. This ATIP thing is hidden by editing registry settings, I am sure.
How can a program tell whether the CD is a CD-R or CD-ROM? (I guess the metal and plastic thing comes in now)
Also, Alcohol Development said that pre-gap is not the only way to get things done, they are using another way which works!
They say it does read pre-gap in a way, maybe not like other programs.
