Does anyone know if this device http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore?productLearnMore=M9319G/A Has an D to A converter or it's just a plug? Does the mini DVI socket have an NTSC signal out on one of the pins? I'm trying to use it for a project that requires downconversion from DVI-D to NTSC composite. The project does not include a mac computer. Is there a pinout of the mini dvi out of mac available anywhere ? Internet or otherwise. Thank you for help!!!!
