Ratso, you should re-read the PM manual/pdf. iTunes is not playing, just running as a background for library management. The Apple remote app works perfectly. That's why Rob designed it that way. And he has many tips and preference check boxes for good remote performance, all described in the pdf.
J Payton, I;m not sure what functionality you are losing. Again, make sure you look at all the parameters in "preferences" to allow for good remote app performance (synching time elapsed, etc)
