Currently Being ModeratedOct 17, 2010 12:20 AM (in response to dgalvan123)By the way I have since upgraded to rme Warner high speed Internet at "up to 10Mbps", though so far I'm getting speeds of 15-28 Mbps. Used to get 1.5-2.5 Mbps on my AT&T dsl.
Anyway, with the higher speeds I now get instant streaming on rentals, HD trailers, HD podcasts, everything. Definitely solved my problem!Mac OS X (10.6.2)

I suspect that, in order to get the HD movie or TV rentals to start playing within the advertised 20-30 seconds, you need to have actual high speed internet bandwidth of at least 4.4 Mbps. Here's why I think that:
Now, in order to get near-instant streaming of this HD content, your actual bandwidth has to be higher than the movie file's bit rate.
Absolutely correct - it's obvious when you think about it - trouble is the advertising blurb makes people assume they get instant video.
IE: you have to be able to download the file at a faster bit rate than the file takes to play.
Yes, and if the rate is slower then it'll buffer an adequate amount of video internally before starting, so that there's enough of a head-start that the slower feed will never run out before teh end of the movie assuming that rate is sustained.
Thus, I submit that, based on the data properties of a real itunes HD rental, in order to get near-instant real-time streaming, you would need a sustained bandwidth of 4.374 Mbps or higher
Your figure is fairly specific to that movie - not all movies will be encoded at the same bitrate - some will be higher, some lower.
This behaviour is nothing new and parallels AppleTV 1 exactly, again the advertising makes people think it's doing something new and clever,it's not.
As an example, with AppleTV 1, as I have a slow connection of 1 Mbps, I would rent on the morning or night before I wanted to view a rental to allow it to fully download, or at least for enough to download and play through without interruption.Mac OS X (10.5.8)

I have mine hooked to wireless network, but if I wire it to my DSL would it be faster? I'm not a techno genius, but I can get by with a little help from people.

Currently Being ModeratedOct 21, 2010 12:40 AM (in response to surfwmn)Wired is generally better for connection stability and speed.
Theoretically AppleTV wireless n is faster than it's wired ethernet port but that's rarely achieved in practice, and it depends what your router supports.
The standard wired connection is more than adequate for AppleTV streaming so if it's simple to connect wired I'd recommend it.
Wired vs wireless however will not affect your internet download speed, only the speed of relay of that downloaded data across your home network, and unless you have a very fast broadband connection your home network usually outperforms your internet speed.

If I were you, I'd go to speedtest.net on your computer and see what your actual bandwidth is before bothering to connect an ethernet cable to your apple tv. If your bandwidth is lower than 4 Mbps or so, it doesn't matter what you do on your home network: you're not going to get instant streaming. That said, I use an ethernet connection to my apple tv, just so I don't even have to think about whether I'm having issues with my wireless network. But it can be a hassle to get the ethernet cable where you need it without it making your house look ugly.Mac OS X (10.6.2)

What is your actual bandwidth, though?
