I too have seen new rotors that are warped. The last set I got it was suggested that I have them turned to true them up before I put them on. At the time I thought it was a foolish suggestion as they were brand new (an we all know that new parts are perfect). I put them on and ran them only to find them slightly and annoyingly warped; I didn't have time to get to them for a couple of hundred miles at which point I pulled them, had them turned and the problem went away. Sounds like it would be worth checking yours....
