    All you have to do is type in the video name in Youtube, then start watching it. Quickly pause it at the start. Then left click on the video screen. Click "Settings". Then untick the box for the option. Hope that helps you. It worked for me and loads of other people. Proud to help!!!

    I disagree with this problem being marked as "resolved", because as mentioned by Lalaru... this would never be an acceptable answer to a client of mine asking me to fix this... not "work around" it and disable hardware acceleration. That's not fixing the problem -- it's only masking it by crippling features of the flash player/your video card. Now, I can say this:

    It definitely has to do with hardware acceleration.

    It is NOT always caused by DiVX, because it's happened to me frequently, and I do not have any extra codec packs, including DiVX, installed on my machine.

    As you know, VLC provides its own codecs and is "encapsulated" so to speak within itself to provide all the codecs, standalone... (independent of the system codecs installed). When this problem occurs (now)... I can fix the problem by doing the easy "disable hardware acceleration in flash" -- OK. then I close out all my browsers and everything... and try to play a video using VLC. Same thing. A green video. A different codec and all. Guess what fixes it? Disable hardware acceleration in VLC! The two are not tied together (VLC is not using Flash to play videos, and vice versa).

    The common ground between the two is only hardware acceleration. That is narrowed down, and is proven that in either program, disabling acceleration resolves the problem.

    This tells me that there is an issue below the codec level, inherently. Possibly the video driver? I have tried messing around with ATI CCC and all the settings to no avail. The only way that I know to fix this issue without "disabling" things is to do a full restart of the computer. Not a big deal for everyone, but I'm always working on a lot of things and it's a PITA to have to save all my places, tabs, documents, etc and stop what I'm working on to reboot.

    There has to be an easier way, WITHOUT rebooting and WITHOUT disabling hardware acceleration. Maybe it's a system service that can simply be restarted? 

    Here's some debug output from VLC when it shows the green screen:

    mp4 warning: unknown box type btrt (incompletely loaded)
    mp4 warning: CTTS table
    avcodec warning: threaded frame decoding is not compatible with ffmpeg-hw, disabled

    That was an H.264 in MP4 container. Here is a WMV file in its ASF container:

    avcodec warning: Physical channel configuration not set : guessing

    It appears to be looking for some GUID's and not finding them, and I'm not sure what "threaded frame decoding" is, but I can guess... but it says it's not compatible with ffmpeg-hw (the decoder) and disables it -- but then turns around a couple of lines later and says it's using my video card for hardware decoding?! Well... I'm looking into this further to see if I can narrow down a REAL cause.

      I bet no one even bothered to read that
      And does it really what it is and if it's a false explanation? If it solves the problem,that's all we need to kno lol no one gives 2 shits if it's not the cause

    Disabling works, just after disabling clear cache,  global settings -> advanced -> delete all delete data , refresh page and check result :]

    although disabling the hardware acceleration solves the problem.. it does not address the root-cause.

    After I put my system through some heavy work I too will get green screen on youtube and other videos like ones I view from amazon s3.  What is the bummer is it doesn't seem like I can fix this unless I close all programs and browsers for a while or reboot my computer.  

    Any clues!

    vlc and divx or just about anything you've installed does not really interfere with youtube.

    youtube uses flash to play content and sometimes its the browser's fault.

    try using different browser to test. i've always have chrome and firefox, just incase one screws up, i switch to the other and it works fine.

    start a youtube video then press pause, right click on the video and uncheck the "enable hardware acceleration" tab. should work.

    Try right-clicking the video, going to settings, display tab (the first one), and unchecking "enable hardware acceleration". That worked for me when I was having similar problems, but I never had DivX on my computer.

    VLC doesn't screw with streaming flash settings, so im guessing the culprit is whatever divx nonsense you installed. Get rid of it, (you only need VLC to play everything), then reinstall the latest version of flash. Restart, and let us know if the problem persists.
