I know this is obvious, but did you clean the disc? My Duo could never make it through the opening cinema scene in Sherlock Holmes 2 and I thought it was a system issue because I had just bought the game brand new. It wasn't until I looked at the disc under a good light that I noticed a barely detectable hazy residue that wiped right off. You should also try a CD lens cleaner, of course . Also, if your CD drive is noisy, use a drop or two of light machine oil (I use sewing machine oil) to lubricate the spindle. Finally, although I'm a staunch advocate for never putting CDrs in a Duo, burning a quick test copy of the game would tell you if a disc scratch on the original is causing the problem. If none of that works, maybe try opening it up and making a slight adjustment to the white plastic potentiometer.
