For both Rock Band and Rock Band 2, i left the calibration settings at 0 video and 0 audio. As a result my drum kit worked perfectly. I need to change it a bit for the guitar but that was just natural wireless lag.
I've played 2 songs so far in this game on my drum kit at 0 and 0, and what I have noticed is just general beats work perfectly but when it comes to drum rolls, either extended or just 3 hits in a roll, the game freaks out and kills the timing window. I havent got a drum roll yet that i didnt lose a streak or miss a note. >.< So what happened.
