Were you ever able to find anything?
I'm struggling with the same issue. WE're trying to use an iPad inside an enclosure for a trade-show booth, with HDMI video running to an LCD screen above for others to watch. The enclosure is not big enough to house the HDMI AV adapter. Ideally I wanted to run a 30-pin extender from the iPad, and use the AV adapter at the end of the extension, HOWEVER, this does not work. Someone mentioned that the apple HDMI adapter has a DRM chip inside.
I'm wondering if an aftermarket AV adapter would solve this issue, and allow me to use a 30-pin extender between the adapter and the iPad.
Anyone have any input they can provide? Or does anyone have a non-Apple AV adapter that they could try this?
Thanks in advance for any help!
