LOL guys, this "disc-0"-protection is THAT EASY the bypass:
simply do a cd-copy with your fav burning app (nero, winoncd) without any subcodes, disc-errors or what so ever. simply copy only the data from one disc to another, u may even copy the content to you harddrive and burn them back on cdr using the same label. this worked PERFECTLY for me. i only needed the use unsafedisc to crack the exe. voila commandos 2 even ran without cd ! give it a try and report back your results!
