Really past time for them to do 1080P now, but since the iTunes store doesn't sell 1080P you've got to wonder if they'll do it. Cheers, Ian

It will pass the digital audio stream directly over the HDMI and optical output if you wish i.e. if the source move has 5.1 AAC and you have a suitable decoder then you can have 5.1 sound over HDMI. > As for the claim it doesn't do 1080p - well it does as mines set to that ! You can set it to 1080p output, however an unmodified AppleTV doesn't have the raw grunt to properly decode 1080p content and hence Apple don't offer any from iTunes. You can set it to 1080p and it will upscale your content, it seems this resolution is achieved by some clever trickery that prevents apps like XBMC using it though. -- -> The email address used in this message *IS* valid <- |
