Ripped a bunch of older TV episodes with handbrake using the ATV3 preset. When I try and watch on my ATV3, however, audio and video are totally disjointed. When I watch on my ATV2, all is fine. It's the same video file being served from my iMac via iTunes. The problem remained after updating to iTunes 11, so that's not the problem. The only difference is watching on an ATV2 vs. ATV3 Ideas???
