Youtube suddenly stopped playing videos

My iMac OSX 10.6.8 suddenly stopped playing youtube videos.
I haven't installed any new software or changed anything that coincided with the loss.
The youtube screen says blocked plug in.
I read the existing discussions and:
  I opted out of the HTML5 pilot, restarted Safari (5.1.8).  Still won't play videos. 
In the past, videos played on Quick Time Player so I'm reluctant to install Flash Player. 
Any ideas??

You cannot watch YouTube w/o flashplayer.  You will need to install the latest version from Adobe's website.  Also, regarding QT install Perian (AVI and FLV support) 
After doing the above installations, make sure you repair permissions and restart your computer.

    I have had the mac bk air for a year now. and it was doing fine, i could watch you-tube, and play videos.

    what can i do?

    test same on a diff. browser such as Firefox or Chrome.
    verify you have Adobe flash installed for video playback on youtube.

  • Projct sequence suddenly stops playing video!

    Hi
    I use FCP 5.1.4 on a Mac Pro twin 2.66 with 3gb ram I have a short but complex sequence to edit. After adding an effect to a clip in the timeline and then continuing to play the sequence I was horrified to see that the sequence would not play any video in the canvas, only the audio. If I double click the individual clips on the timeline so they open in the viewer - they play.Now, if I play the sequence it is fine up until the point where the problem first manifested, but beyond that point, everything goes black!!

    I reverted the project just to get moving , it was a third party effect, but this has since happened again when doing some picture-in-picture stuff. I answer to the previous suggestion, it is nothing so basic, I even get wireframes displayed in the canvas and everything, but no image?!!! When I try to play it through external video, it displays the last frame that I paused on, until I pause again, but won't play the sequence.

  • My macbook has stopped playing videos, why?

    Macbook has suddenly stopped playing videos.  Please help

    Be sure to look at the Settings for Videos, on iPod.  From the main iPod screen, select Videos. At the bottom of the Videos screen, select Settings.  Make sure there is nothing unusual there, particularly in TV Out.

  • While playing videos from YouTube it stops playing on my iPad2

    While playing videos from YouTube it stops playing on my iPad2

    Try to download the application VLC.
    It is a media player that should be able to play any audio or video file you may have. If your videos play flawlessly using that application, then the issue is with iTunes and Quicktime, as they are both essentially similar software types when it comes to playing media.
    In that case you may need to install a plug-in file called Perian, in order for the videos to play correctly within iTunes or at least Quicktime...

  • My iPhone 5s stopped playing videos from web, Facebook, youtube, instagram etc. What should i do?????

    My iPhone 5s stopped playing videos from web, Facebook, youtube, instagram etc. What should i do?????

    Hi 361,
    If you are having issues with your iPhone not playing video from any source, you may want to try some things to troubleshoot.
    First, quit all running applications and test again -
    iOS: Force an app to close
    Next, I would try restarting the iPhone -
    Turn your iOS device off and on (restart) and reset
    If the issue is still present, you may want to restore the iPhone as a new device -
    How to erase your iOS device and then set it up as a new device or restore it from backups

    When you first import your video, before you do anything, do you have a red line over the video on the timeline?
    If you do have a red line as described above, your project and your video do not match

  • Many of my older ITunes downloads play perfectly well on my IMac but constantly skip to the next song or suddenly stop playing on my IPhone. The problem is the same with both my old 4s and my new 5s. I have tried deleting and re-downloading to the phones.

    Many of my older ITunes downloads play perfectly well on my IMac but constantly skip to the next song or suddenly stop playing on my IPhone. The problem is the same with both my old 4s and my new 5s  phones. I have tried deleting and re-downloading my music library to the phones, but the result is always the same.

    I'm adding more information:
    in Finder, my iMovie folders are all visible and accessible.  When I click on a clip from iMovie Events folder, Quicktime opens and plays the clip.  ALL my video is not missing - it just isn't showing up in the Event Library!
    This happened all of a sudden, while I was working on iMovie project (on both computers).
    All my Projects are intact, and play when I open them.

    Try resetting the iPod...

    Also, is this with all videos or purchased ones? Do purchased songs work fine?
    Finally, see if this sample video works (the one for the iPod)...

  • My Mac has suddenly stopped playing my DVDs including a DVD it played fine only 3 days ago. Does anyone have any idea what could be wrong and how I could fix it? Thank you.

    My Mac has suddenly stopped playing my DVDs including a DVD it played fine only 3 days ago. I insert the DVD and wait for the player to start automatically but after 10 minutes, nothing is happening and it sounds like the disk has stopped spinning. I've now tried with four different DVDs (all store bought and so perfectly normal disks). The Mac doesn't eject the disk or anything it just doesn't seem to respond to it being there at all.
    My main confusion is why this suddenly happened today when it was perfectly fine last week.
    Does anyone have any idea what could be wrong and how I could fix it? Thank you.

  • TS3700 why does my ipod suddenly stop playing

    Why does my ipod suddenly stop playing?

    is your battery charged?  How many songs do you have on the playlist (if you are playing a  playlist when it stops)?   I know that when the earbud wires are accidentally disconnected from the ipod body, the music stops automatically.

  • My Mac suddenly stopped playing through my external speakers which are fine and working well with other devices.

    My Mac suddenly stopped playing through my external speakers which are fine and working well with other devices.

    Have a look in System Preferences -> Sound -> Output.
    Plug the speakers out. Do you now see "Internal Speaker" as the name from the Built-in device? If you replug your speakers, is it now changing to "Headphone?
