I have had my Surface for a couple weeks. I have maybe five apps installed and maybe two other programs, that is it. One is the most recent version of iTunes 64-bit downloaded directly from apple.com. When I go to watch TV shows downloaded to the hard drive from the iTunes store (not streaming), I get a stutter. It starts fine, then after a minute the audio gets more and more out of sync with the video, then after a few minutes the video itself starts to jump frames. I know the tablet is powerful enough, but I can't figure out why with stock software (iTunes right from Apple) and other minimal applications running that the video won't play correctly. Anyone else experience this? Thoughts?
