Hello all.

 

I notice this only recently.  Do not have this problem before.

 

When I play a YouTube video, say a new music video in HD either 1080 or 720 at full sceen (I will wait till the entire video is loaded)

 

There will be a regular interval of a "split second pause" or "skip" throughout the whole video play, otherwise the video continues to play, audio is not interrupted.

 

If I do not play full screen this will not occur.  So now it sort of "spoil my fun" to watch at full screen because of this small little "irritation and annoyance".

 

Any idea what is going on and how can I solve it?

 

Thanks and cheers.

    Check Safari / Preferences - Extensions. If you have any installed, turn that off, quit then relaunch Safari. Try a video.

     

    If it's not extensions, try Troubleshooting the  Flash Player for Mac OS.

    Hello Carolyn,

     

    Will try that. Was quite late last night. Have turn off all extensions for Safari, and in fact, I have reset Safari and deleted all the existing cookies.

     

    Now that you've included the link to troubleshoot Flash players.

     

    I recalled recently I just wen to Adobe's page and downloaded and installed the latest Flash Player and Shockwave player.

     

    Are these two the "culprits"?

     

    But anyway, like the troubleshoot page explain, I was watching some latest YouTube music videos with the Vemo branding, and I doubt they are build-in flash, but maybe HTML5 instead?  I'm not sure.

     

    Anyway, will try again and see if it helps

     

    Thanks and cheers

    Deleting Safari cookies may not have any effect on the video, but you can flush Flash cookies following the instructions at this link.

    Thanks! This is very helpful.  Will try tonight!

     

    By the way, to be on the "safest side", should I just re-install Safari?

     

    Cheers

    Hi.

     

    I've dome all I can:

    • Reset Safari, deleted all the cookies, etc
    • Flush/Deleted the Flash cookies as Carolyn have suggested.
    • Reinstall Safari

     

    And STILL, same persisting problem, regular intervals of split-second freeze frame...

     

    To prove that there is nothing wrong with my iMac, my internet connection etc;  I downloaded Chrome and tested it, play a full screen YouTube video, in fact the same one, I log in using my same ID, i.e. into my YouTube account, and the video play perfectly normal and fine in full screen HD size 1080.

     

    It may be bit troublesome and inconvenient, but until Safari has fixed or come out with a solution, or if I find one, but before that, I am sticking to Chrome to watch YouTube videos.

     

    Thanks and cheers

    Quit safari then delete the preference file ~/Library/Preference/com.apple.safari.plist and reopen safari and see if it works. If it doesn't then quit safari and delete the file again then do the next step.

    If you don't mind deleting your bookmarks and other data quit safari and delete this folder ~/Library/Safari.

    OOOHhhh one other thing is that I noticed that when I used Chrome a lot my screen occasionally flickered. I ran the hardware test and nothing came up so I reduced my use of chrome and haven't had the problem.

    Hello Chris,

     

    Thanks!  Okay will try tonight to delete Safari's pref file and everything else;  Have back up anyway. :-)

     

    Maybe I'll update to 10.6.8 first and see how it goes

     

    Cheers

    OK this is "terrible".

     

    I've updated to OS 10.6.8, and did all to Safari:

    • Delete preference file
    • Delete the whole folder

     

    and start all over.

     

    Play a YouTube video, any video, now even at a norm window mode at 360 or 480 res, the video still "freezes and startles"... I really am lost and don't know what else can be done.

     

    I thought it was my Norton Internet Security, so I turn them off, still same.

     

    And using Chrome does not seem to be affected by all these.

     

    Cheers
