Can't get this app running on the net for some reason. The wifi works great, but trying to access files via 3G is not working. Something about not being able to resolve two routers, but I only have one. Seems like I've always had an issue with this app.
Gave ZumoCast a shot, and it's interface is MUCH easier to use than Air Video. However, the 3G over the net operation is horrible. Very blocky, choppy, and might as well not even use it.
Great apps in concept, but there is still some work to do.
