Hopefully folks will be civil ;-)
No shame in voting with your wallet though
many (my friends and I) were able to fix this issue by simply
configuring the Apple TV not to sleep. As for
putting your movies on a NAS, you can accomplish
the same thing with Air Video, a $3 app, that lets
you transcode on the fly and send videos to your
Apple TV via AirPlay. Used it for years and it works
well.
It's good to have options though. That being said
(puts on Apple fanboy hat) Google TV hasn't exactly
set the world on fire and the Nexus Q selling for $200
more than an Apple TV probably means it'll end up
being a hobbyist device for Google too. If you've
invested in the iTunes ecosystem it's difficult to make
the switch. If your content is DVD's you've ripped it's
easier to be agnostic. Apple really should fix this bug
though.
