I just received my new white Macbook with the Nvidia 9400m gpu. I can get the mini dvi to display with a DVI adapter, but the mini DVI to RCA will not work. The dongle lowers screen resolution, which tells me the laptop sees the adapter, but I cannot get the video to push out using RCA or SVideo. The adapter works fine with a 2.66 iMac and an older 2.16 macbook, so it is not the adapter. Anyone have a work around for this issue?
