I installed the new combo 10.6.3 v1.1 update on my 1201 and everything seems the same. No difference at all; the only reason i installed it was because i am hoping that maybe somehow (in the future - one can hope) i would be able to have HDMI audio through the cable. The new MBPs that came out today support this and this update was posted on apple's site yesterday (4/12/09). But to answer the question, no problems and no difference with the new update.
