Recently rediscovered Air Video HD after using the older version of the app many years ago. I bought both the Apple TV and the iOS version last night. It's literally almost exactly what I was looking for with the exception of a few minor bugs and a few small areas it could be improved.
I would really like there to be a list view on the Apple TV app, just like how there's one on iOS. My preference is to see my long filenames! Surely as the code already exists in the iOS version it should be a fairly trivial matter to port it over?
Maybe there's a nice way to use all that extra space on the right side of the list, like maybe a large image of the cover art that changes depending on what file is selected? I dunno. But failing that, just a simple list would be a good start.
