Thanks Dave,
So when you open iTunes you see multiple devices?
Any screen shots you can share?
And also, I'm not understanding how if works through the Airport N Basestation when the G5 has built-in Airport, etc... I tunes bypasses the built-in connections and sends things from the computer to the external airport N, then wirelessly to the devices?
Yes, when you open iTunes you see both ATVs providing you have both ATVs syncing to that Mac. In our case that is the way we do it. Both ATVs sync to my Mac Pro. However, both ATVs also stream from either my Mac Pro or my wife's iMac depending on what content we wish to watch since we have different content on both Macs. In iTunes for my wife's iMac, you do not see either ATV since her Mac is not syncing to either ATV; iTunes only shows those ATVs that it is syncing to, not those that it streams to. In the ATVs source list you see both my iTunes library and my wife's iTunes library as choices to stream from since both Macs have been enabled as streaming sources on both ATVs. This sound complicated, however, its is really simple when you actually do it and its well documented in both the iTunes and ATV help files.
When you use the Apple Extreme "n" router, your Mac streams to the router and then the router streams to your ATV. You Mac never streams directly to a ATV. However, the new Apple Extreme "n" router is so fast that you can easily stream two different movies to two different ATVs at once with no problems at all. In fact, in my home (all on one floor) I can stream three movies to two ATVs and one laptop at the same time with no problems. I would not have any problems supporting three ATVs at once I'm sure.
As far as I'm concerned, the ATVs are fantastic and will only get even better as Apple upgrade the ATV firmware to add new features at time goes on.
Anyone that complains that the ATV is a flop does not understand what the ATV was designed to do and is unhappy that it is not what they wanted it to be, not what it is. In that case, just don't buy it. But for those that want a way to stream their entire iTunes library to their large screen HD TV, the ATVs are perfect!
I have ripped our entire DVD movies and TV show library in high resolution format (ATV preset) using Handbrake for the ATVs and they look very very good, much better then they did when played by our DVD player. The best part is that with all the content only a click away we can now find it and watch it without having to search drawers, racks and storage cases just to find the program what we wanted to watch (which prevented us from watching DVDs most of the time).
We are waiting to see what the next version of the ATV looks like before we purchase a third unit to put in our guest room. We have had visitors who were die-hard PC users until they saw the ATV. Now several of them have purchased their first Mac, Airport Extreme and ATV and are planning to move to the Mac completely. I think that Apple is going the right direction in its marketing planning for the first time...the ATV and the iPhone will bring more PC converts into the Mac fold then just about any thing else they could have done.

Hope this helps,
