Hi everyone - just set up my new apple TV3 - and the install was pretty easy... its hooked up to the wifi network and homesharing is on. I've moved some of my own DVD titles in to the Movies section of my iTunes Account and settled down to watch a movie this afternoon. The problem is, is that it keeps stalling every 5-10 minutes whilst it buffers for between 30seconds and 10 minutes each time - which is pretty aggravating!


Picture and sound are perfect - its just the continual pauses...


Its streaming music seamlessly and Photostream also. I decided id try watch a movie trailer on the itunes store and it took over half an hour to down load an 8 miniute clip.... this cant be right surely ?  


Can any one help ?


Set up is iMac 2.8GHz desk top, with a time capsule on ethernet, and a BT Broadband Home Hub 2 Router. Download speed varies between 5-6mbps and wifi is strong.

iMac, Mac OS X (10.7)

    Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.

    You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.

    Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.

    There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software. You might also try moving the Apple TV away from other electrical equipment.

    No that doesn't sound right at all.


    First thing to investigate however would be the networking.


    AppleTV requirements for streaming are modest:


    2.5 Mbps for real time streaming of SD, 6 Mbps for 720p and 8 Mbps for 1080p - once enough has buffered it should just play through provided the same throughput is maintained.


    Trailers in SD should play near instantly if AppleTV is getting the 5-6 Mbps from the internet you suggest, unless your LAN is very slow for some reason eg concurrent usage or poor wifi.


    Ic onnected by wifi, how many bars of wifi signal do you see in Settings>About>General?


    Normally I'd expect the LAN connection speeds to be far better than internet speeds.


    Other things to check are software firewalls which might see repetaed communications as intrusio attempts.

    There appear to be a few issues going on with Apple's servers at the moment. Alot of people are seeing problems with their Movie and TV Show icons dissappearing.from the home screen. Apparently Apple are working on their servers currently (although we dont know for sure if this was planned or unplanned).


    When the Movies icon is visible - streaming movies and trailers is very slow.


    I've looked at the traffic going to and from Apple's servers to my own ATV and can see the the traffic is being delayed at Apple's end - so my first thought is that your problem is related to the work Apple are doing at the moment.


    Obviously check your connection locally as advised by Alley_Cat and Winston Churchill - but if this doesnt resolve your problem then keep an eye out on these forums to see when this other issue gets resolved and try to stream a movie again as that may well be the cause.

    I've just tried streaming the ripped DVDs on my iTunes to my 4s and my iPad - both appear to streaming fine with no stutters - which points to my network being ok and it being an issue with my ATV3 ?

    Not necessarily - assuming wifi - one device may be in a better location or have better reception than another.  That said it may well AppleTV, iTunes or router/networking.  No harm restarting router if you haven't done so.


    With regard to interference, our microwave used to regularly cause issues until I moved it.


    Note - discussing use of ripped DVD content is in essence against forum rules, avoid mentioning it.

    When I tried the 4S and the iPad I was sat within 2' of the Apple TV. I haven't tried rebooting anything so I'll give that a go... would there be any merit in trying turning off the wifi on the BT Homehub and using the wifi on the Time Machine to see if that improves it ? or Would an airport extreme base station help ?

    From what you say it is likely that wifi is ok, but remember that each device is unique (even faulty wifi on AppleTV???).  Can you move AppleTV a little in case interference from adjacent devices is the culprit?


    If there is any way you can hook AppleTV up via ethernet it would be handy to narrow it down to a 'wifi issue of some kind' or not.


    Personally I have used Devolo powerline home networking for AppleTVs for quite some time but they may not suit everyone - wifi is great when it works but not when there are issues.


    Always worth restarting:


    1 - computer and iTunes

    2 - AppleTV (unpower if you can first)

    3 - Router


    This is not a precise art - I have found my system can work fine for months and then plays up - sometimes it's the AppleTV, sometimes iTunes, sometimes the router which need a kick up the backside to get things running again  


    Be assured AppleTV works very well, but occasionally things affect performance that can be tricky to track down.


    As a last resort consider resetting all setting on AppleTV, setting up from scartch or a full system restore of current firmware via iTunes.  Also if within warranty and wifi seems unreliable consider an exchange in case you have a lemon.

    Alley Cat.. Oops Sorry - I do own the originals!


    In some ways it would be helpful to know that a 'gold standard' iTunes purchase (f re e TV episode for example, or check the 12 days of Christmas freebies over next few days if in UK) plays up too, as otherwise you'd have to consider encoding issues with non-standard files.
