Sorry Spine but it's not going to work.... I did the same thing hoping to finally get an output on video. You probably are getting audio sound but no video. "Airplay" is the same way. Actually I am really disappointed but hope Slingbox will come out with another update that will add video out for their customers. Sorry for the unfortunate news but there are a lot of customers out there posting about this and seem to be rather upset about the issue.
Hi, Spine81doc and cbras
The TV-Out feature is currently available for the SlingPlayer Mobile application on your iPhone. The following link will provide you with further information.
I have the iPhone 4, slingbox solo, apple video out cables and use the slingplayer app on my iPhone to watch video through my in car video system. However this only works when I'm parked in my garage where I can get strong enough wifi signal to run the setup in HQ mode. As soon as I try to drive anywhere the signal reverts to SQ and I lose the video. (AT&T just doesn't provide enough signal locally to provide HQ over 3G cellular).
Developers PLEASE remove the HQ retirement.!!! I don't need HQ to enjoy video on my incar LCD monitors; SQ would be just fine. I've spent a ton of money to set all this up and this is the last thing that's holding up an otherwise slick setup.
By the way (it's for video In the reAr seats so not breaking any laws here:)
