Oops, I mispoke, John, and you trusted me, unfortunately!
It's 4.2 SP1 that leaves out Roxio...I have 4.2 SP2 installed (was getting some calendar sync errors w/4.2 SP1 so thought I'd see if going to 4.2 SP2 helped) and 4.2 SP2 has an earlier version of the Roxio Media Manager.
So go 4.2 SP1 to skip the Roxio media manager...
