Sure even though I know some people wont agree.
Apps I've tested include:
PIE and PIF numbers, 1 being least and 5 being highest.
RecordNow 4.5-4.6 = 1
Nero = 2
DiscJuggler = 3
CopyToDVD = 5
Alcohol 120% = 2
DVDDecrypter = 2
From my test CopyToDVD always had an unusual amount of PIE and PIF compared to all the other apps. I can't explain this. I have tried over and over with new version and get the same results. DiscJuggler was a litte high too but not as bad.
The apps I rated 1s and 2s were very very close.
I'm probably forgetting about some. Those are the ones that stand out in my mind.
