I have a S2 Tivo connected to my cable box with the serial cable. Occationally when I press the channel up button I end up going up several channels, one at a time. I swapped out the cable box but the problem persists.

My next thought was to switch out the serial cable, agreed?

Check for IR interference. You are still using IR to the TiVo and if it is getting interferred with, you'll see this kind of problem.
