    Even though I love rev A screen to me it is useless if can't watch video on it. I have tried HD video on several rev A's and none can handle it. I am leaning towards a MBP instead...

    any flash video will have problems. flash does not utilize the GPU very well. are you using flash 10? I have heard that helps. Also, if you are on youtube you can get a javascript widget to play the video in quicktime instead of using flash.

    Yup, I'm running it on my 40" Sony Bravia LCD and went to CBS.com like you pointed out and watched Criminal Minds, and the Insider and everything is totally awesome, so you've either got a problem with your MBAir or your tele is tossed up. Sorry, but both my TV and my MBAir are working just fine...:cool:

    Well I tried several MBA rev A in stores and they could not handle the HD videos on cbs.com.
    I even noticed that a rev B 1.6 HDD had more blocky graphics than a 1.8 SSD.
    so the question is if you guys that don't have problem with your rev A and HD shows on cbs have the SSD model?

    Anyone have any other explanation?

    SFStateStudent do you have 1.6 or 1.8 and is it HDD or SSD and finally is it Rev A or rev B?

    Thanks

    Apple store loads stock install and is not the best way to test a rev A since resolving issues require monitoring/installing software.

    But Rev B handled it no problem.
    Btw, since I heard that cbs.com uses flash for its content could that be why the 1.6 HDD Rev B version did worse (more pixelation( than the 1.8 SSD or is it a matter of SSD vs HDD or 1.6 vs 1.8?

    Thanks

    If it weren't for the HDD vs SDD difference, I'd suggest maybe it was the internet connection.

    But if the SDD models streamed the video fine, your guess is as good as mine.....

    From my experience, the rev a I owned for a brief moment couldn't handle ANY 720p. Didn't matter if it was streaming, flash, saved on the hdd, whatever.

    On the rev b I have, it still stutters on flash video. I wish Apple would fix this already. It's quite pathetic that it can't play flash flawlessly yet. The MSI Wind I had before this could handle flash MUCH better than the Air.

    Hi

    I tried the set up on one HDD and SSD Rev B next to each other on several occasions sometimes starting HDD first and sometimes SSD first so internet connection was not an issue.
    Dont get me wrong, if I hadnt run SSD next to the HDD I might have missed it but when I looked how it handled some backgrounds it was bovious the SSD (1.8) was doing a better job.

    Since it was streaming I am leaning towards the CPU being the reason for the difference. But that means that 1.6 is borderline being able to handle it.
    At the same time when compared to the old A rev they had and I didn't use a full screen mode the Apple guy said the extreme difference i blockingness even for a small picture was due to the improved GPU in the new machine. Then it begs the question again, why a difference between SSD and HDD???

    Anyone have a theory?

    It may/may not have to do more with CPU speed than HDD/SSD speed.
    You would need to download coolbook (free version) to watch what CPU speed each MBA is jumping to. Most of the tests I've done, the new SSD would stay at 800mHz and jump to 1.6 rarely getting to 1.8 which lead me to believe that 1.8 (for my needs) wasn't really worth the extra money.

    It's Coolbook, simple as that.

    With the latest updates, OS X throttles the CPU speed upon heavy usage. That was their solution to the core shutdown problem. Ironically, it makes the Rev A act as if a core was shutting down.

    If you install Coolbook, and leave the CPU limit to something like 85 degrees C, it will not stutter (nearly as much).

    And where did someone get Braveheart High Def DVD?

    But please note that the 1.6 and 1.8 I tested were both Rev B. That is why I am unable to determine if it is the SSD or 1.8 that is needed for perfect HD video.

    I had Rev A and had video issues all the time. Since I purchased Rev B all is fine, I would recommend against the Rev A if you are into video.

    I'm watching HD video on CBS.com right now with my Rev A (HDD) MBA without any problems.

    I'm also running Windows 7. OSX made this thing run hot and slow. Vista and Windows 7 have been great on it.

    YMMV

    Yes, specifically streaming. But, there are some like the poster above that have no issues.

    do you have more information on OS X throttling the CPU on heavy usage? I'll really like to read up on Apple's "solution" so i can decide if coolbook or the os x update is better.

    thanks

    For those of you watching the HD video on CBS, ware you using full screen mode?

    And have you upgraded to Flash 10? Because if you are doing it on Flash 9 just like the store copies have there is something weird going on...

    Are you serious? Windows plays/runs HD video better without problems??? Bootcamp or VM?? WTF!!

    Somehow I have a hard time believing Rev A's can play HD video without stutter...

    Flash on Windows is way better than OS X.

    Hardly the fault of Apple, or OS X.

    I read your post yesterday while at work, so when I got home I decided to test my Rev A SSD to see how it would perform playing HD shows from cbs.com.

    Well, I had Safari window open, surfing and played NCI: Miami (or is it NSI: Miami?). Well, there was a little bit of choppiness 20 minutes or so into the 43 minute video but the computer seemed to have gotten over the hump and the rest of the show played normally. The video might have played normally if I had no windows open.

    So, for me, that is fairly acceptable performance and I don't have CoolBook. Perhaps the performance will be even better once I install the program. The fans were silent, but hot, at around 6200rpm.

    interesting, have you run it full screen? If that works then the difference is the SSD since the rev A I have tried have all been HDD...
