OK.....due to my mixed ATV environment (5xATV1 + 1xATV2), more and more of my library is not accessible on most of my ATVs as I rip for the higher specs of the ATV2. But Ive just ripped a mini series in HD, and because my wife wants them accessible on our bedroom (ATV1) system, and knowing iTunes supports a single listing of dual resolutions of the same thing, I thought to give it a go. Well, works a treat...iTunes has the HD/SD icon beside the names...but how in hell does it know which one to play? Because when I tried playing it on a ATV1 unit, it obviously accessed the HD version as it locked up/behaved sluggishly(under statement)/required a reboot (at the wall). Anyone know?? Is it a play/button combination on the ATV remote?? I ripped both versions in HB, selecting ATV2 and ATV preset respectively.
