I have an ATV2 and recently got a new 50" 3d Panny TV, which is stunning but now I want to try the 3d part, I managed to grab a 3d film but it seems quite slow to respond at times, as the film is much larger than my other 720p film collection. I also borrowed a friends 3D version of Avatar which plays on his ATV3 but wouldn't play on mine at all. So was wondering could it be my wired net connection to the ATV or maybe the ATV3 has a lot more power to handle the bigger file size, ram buffer cache etc.. Currently I have a cat5 cable going from my main router (Sagecom F@ST2504n) to a Netgear GS605 switch hub under the telly I use the hub to spread net connection to ATV, Xbox, Onkyo amp etc but was wondering maybe I need Cat6 cable and a better switch box or whatever it should be so I get a 1Mbit connection, not sure how to test what speed I'm getting, maybe I can plug my Macbook Pro in to check. Ahh I think maybe an ATV3 would be worth it as I could start converting my films again to 1080p, so far I haven't noticed any real difference, but maybe with this telly I will. Appreciate any help or advice.
