i have a lite-on 24102b (24x10x40) and it has never giveing me a problem with copying any games out there, i have copied medal of honor which is one of tha hardest games to copy.

i have tha newest firmware 5S57 get it from

http://www.liteonit.com/index-english.htm

also make sure u have tha newest version of clone cd (4.0.0.1)

also make sure u dont use a cd-rw drive to play them games back because of atip protection, if u do u have to enable hide cd-r media option

good luck
