I've been using Infuse on my iPads to watch movies from my smb share for a while.
However, the problems are still the same with many of my movies, and they persist between versions of the product (e.g. gray square appears at the bottom of the screen, movies refuse playing mid- process, hangs, stops etc). I think that mostly these problems affect HD movies (1080p and up)
Am I using the best configuration possible? I stream content to my big plasma via AirPlay over 5GHz WiFi. Maybe I would better off purchasing Infuse for AppleTV? is it better at playing HD content? How hard it would be to navigate smb folders with content? Can iPad still be used to navigate, view and select my movies, and AppleTV will do all other heavy lifting related to decoding and playing, without airplay streaming involved.
