I want to output the video from my 2007 iMac via its Mini-DVI port and the audio out via the headphone port and combine the outputs to a single HDMI output to send to my HDTV. The device below looks like it should do the job: http://www.ebay.co.uk/itm/200966407684?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 However, it has a female DVI input port. This means I need a male Mini-DVI to male DVI converter. No such converter seems to exist. How can I make this work?
