I use both Alcohol 120 and Clone CD. I use alcohol 120 for everything except Securom games! Clone CD in my opinion does a better job of Securom! When backing up a Securom game using CloneCD just choose the 'Game Protected CD' setting and you will have no problems with the backup! You will still need to use a NoCD crack to play the game but you wont have to bother with the DPM measurements!
