Hi folks!
This REALLY works for me.
All you need is the newest Alcohol 120% and an Empty DVD R+(don`t know, if this is really important...).
You have to turn the RMPS Emulation ON (Alcohol Emulation Options).
Then read the original Disk with Alcohol, use HIGH DPM (1X speed)
You MUST use a DPM capable Drive (in my case, it was the DVD DL-Burner, NOT the "normal" DVD drive)
If everything went ok, just burn the image on a 4,7 GB DVD (+ works, don't know if -, too) WITH "RMPS".
The newly created disc has to appear with the real name, and not with the label "NEEDS EMULATION". If so, you have forgotten to enabe RMPS in Alcohol.
OK, just remeber, that this backup procedure worked very well.
Now I can play and keep my original disk scratch-free
Try it out and post, if it works for you as well!
Cheers,
Thomas Posso
