So lately I've been having a really weird issue with video playback on my MacBook. It has never really cropped up before this past week or so, but has gotten extremely common the last few days. What I do is I'll be watching a video on Netflix, NHL.com, YouTube, whatever. It's usually when I hop between tabs with the video open that the distortion is most likely to happen - I typically jump tabs with either Ctrl+Tab or Cmd+Option+Arrow. Software is up to date. Adobe is up to date. I typically run Chrome and this issue due to it being less finicky with certain sites (NHL.com for instance), but due to the common place nature of this bug, I tried using Firefox and it gets the same issue too. I've got a link below showing what sort of happens. Sometimes it's worse with a very high pitched robotic distortion that kind of carries on even after closing the tab. Although this clip isn't the worst, it actually fixed itself right after, which doesn't happen often. Typically the video lags/freezes, the audio gets unsynced, and the audio gets distorted as in the video. Usually I have to reload the page entirely. Any thoughts? http://dl.dropbox.com/u/12848871/video issue.mov - Just click to stream. Also sorry for the size. I chose the web export and that sure did compact the file as well as the resolution, but you get the picture. I had The Office (UK) in Netflix and was just flipping over to the exit polling data on CNN.
