I just got a G5 1.8 Dual and have an S-Video connector I would like to run to my 720p tv to view my itunes movies. I am using the s-video in on my HK receiver. The picture is pretty sharp, but it is in black and white. I am running 10.5.8, and I have the same problem when I connect my MBP running 10.6. Any suggestions? No worries. A direct connect to tv solves the problem.
