    Have had my MBA 11 for weeks now and it works great so far.

    I have been watching HD YouTube and Vimeo videos with no problems but I noticed last night that some Vimeo vids are really choppy when played full screen. Here's a really good short called Blinky TM (for all you horror/robot fans...you'll love it!!!) that exhibits this:

    (Please play in full screen)

    Could anyone with the same MBA let me know if this problem is universal? Results from slower and faster MBA's also are appreciated.

    Thanks for your help. :)

    11" MBA 1.4ghz, 128gb = No issues on playback... likely something is tying up a system resource or something installed isn't playing nice. Backup and do a clean restore and try again. Worst case if it doesn't fix it, you can restore the old backup and don't lose anything. Have you checked on alternative internet connections? I'm on Comcrap 25mbit, but i know some other providers do some strange bandwidth "optimization" that can cause issues for HD playback... unlikely but something....

    Sorry but did you play it in full screen?

    Yes.

    It's got to be a software issue where something you have is conflicting. The MBA specs are 10x what you need for this type of playback, so it's not a hardware performance issue.

    Thanks. I tried to run it on Firefox and it ran smoother. You're right, there must be something on Safari. Checked resources but cannot find anything hogging anything.

    I remember restoring from Time Machine when I first got my MBA so a fresh install this time around might do the trick.

    Thanks again. :)

    Ever since the last Safari update I've been underwhelmed by it's performance.

    When the new firefox came out, I'm baffled as to how much faster it runs than safari. You'd think Apple would be able to make a faster browser given they make the OS, the hardware, and the browser. It's beginning to cause me to question apple's direction.

    Done re-installing OSX but the problem still persist. I am baffled. :confused:

    That video was stuttering for me too at about 2 minutes. I paused and let it load which fixed it then it started to stutter again at about 9:45 (i like the video btw thanks). I have an older MBP, not the MBA, but I can tell you I've been watching full screen flash movies off Hulu and in HD off Netflix for years without stuttering. I googled and found an old thread on the issue, but I don't think there is a fix. I think its just strange behavior. http://discussions.apple.com/thread.jspa?threadID=1666546

    For the video you showed if i let it sit for a while, even if it looks like its loaded plenty in advance it would eventually play without stutter. The thread i linked you mentioned something about a 30 second wait?

    No probs. :) It is indeed a well made short! I need more Blinky now...hehe :(

    A while back, I have uploaded my own HD videos on Vimeo and followed their requirements for uploading 720p. My videos are mp4 encodes at 5000 kb/s. They do not play well full screen too. :( Could it be the 5000 kb/s encode, I wonder.

    Plays flawlessly on the MBA in my sig. Once I let it load for a bit, that is. I have ClickToFlash installed, so it loaded a non-flash version. Maybe that made a difference?

    Great video, as well. Thanks for the link.

    Thanks for your input. This leads me to believe it's the Flash plug-in for Safari that's the culprit.

    I am really worried that my unit is 'throttling down', totally unexpected but a possibility. Stuttering also happens when I play my home made mp4 1080p video played with Quicktime. I don't remember this happening on my friend's 11" ultimate.

    Will have to go to a Genius tomorrow. :(

    No probs.

    I noticed that the this video file is 1920x1080 as opposed to 720p.

    UPDATE:

    Just got back from the Apple Store. Spoke to a Genius and she couldn't believe this was happening. I tested their demo MBA 1.4 2 GB and they ran the video flawlessly.

    Got a replacement brand new unit and it ran the video like butter in the store. I am now migrating my files and updating necessary apps.

    Forgot to mention that the defective unit had its fans running like crazy when I attempted to run the video last night.

    Will let you know how it goes from here.

    There are fans in a 11" MacBook Air? I've never heard mine, and I do video encoding a lot... if I heard fans in a MB Air I'd be concerned, lol.

    Yup, they're exhaust fans I believe.

    LOL...I was worried alright so I didn't hesitate to bring it back. :)

    My iPad played it flawless, but only after it downloaded far enough, the download was quite slow.

    Update

    UPDATE:

    After updating to 10.6.7, the choppiness returned. I am now convinced 10.6.7 is not optimized.

    To all who posted here with no problems, did you update to 10.6.7?
