    You may have an outdated version of FlashPlayer.Uninstall FlashPlayer. Install the newest version here.
    Repair permissions after the update.

    More of the YouTube content is higher resolution videos these days...

    It can probably play lower resolution videos without problems. Higher resolution videos may drop frames, especially if you go to full screen mode. HD video, you might as well forget about playing.

    You may also get better results if you pause the video until it downloads completely, then play it. Downloading while playing the video is more processor intensive. Also, if there are Flash animation ads on the screen, adjusting the size of the window so only the video portion is displayed will allow the limited processing resources of you older Mac to focus on the video.

    Thanks guys

    I tried everything you suggested.. But its still the same.. Surely my imac can handle youtube and maybe it's something a bit more simple to fix?

    i thought i read about the flash player being poorly coded for macs and there for use more of the processor. as you can see in my signature that i have a 1ghz processor and enough ram and i still have problems with youtube. even if i shut all the stuff off on my computer it still uses 90-100% of the processor.... maybe try the firefox browser i think that works better then safari for watching flash videos, search on the net to and see if there are any fixes out there?....

    I reckon there is nothing at all wrong with our macs - it's FLASH version 10 I have never had any problem viewing streaming video from news.bbc.co.uk and bbc iplayer and you tube, on my imac G5 2.1 Ghz PPC, until very recently. The same material plays fine on my macbook intel - so my internet connection is fine. BUT HERE"S THE THING - if I switch to full screen mode the video is fine, no jerkiness or choppyness. Its FLASH that's at fault and someone should fix it quick.

    Also try upgrading to Safari 4 - that seems to solve the jerky video issues

    I have a iMac G4 1Ghz with only 512mb ram, it runs Leopard right now, and using the following site's tip, I am able to watch youtube video without lagging (In fact, it runs surprisingly smooth).


    The link talks about using Quicktime Plugin to load youtube videos, and it works great.

    P.S. I have noticed that some of the youtube videos cannot be played using quicktime plugin....but most of the videos are tried worked flawlessly.

    (I replied because i was searching for the answer taht you are looking for all over the web, and I saw you post several times already! )

    I just remembered that i saw this:


    It's a HTML5 demo of youtube, which means it doesn't use flash player to show video...

    Details of it here:


    HTML5 could be the savior (no tweaks needed!) for our youtube watching!

    The other issue may be your internet connection. If it's wireless 802.11b that can also give you those symptoms as you may need a faster connection...... if you are dialup then you will need high speed....
