iBook G4 Video Lag

[apeckerhead]

What can I do to stop my mac from lagging with viewing videos from sites such as google and youtube and sometimes music cuts in and out? It seems to be slow and requires time to think especially when more then one window is open or multiple tabs are being used. Would a simple ram/memory increase solve this problem? Also sometimes a message regarding quicktime pops up and says I need to update even though everything is updated to 10.4.11 max. Also what is being used to download music.
Thank you.

Those videos you're watching most likely are embedded into Adobe Flash, which sucks on the CPU like a thirsty calf on a dry mother.

You can use Click2Flash to watch YouTube videos via QuickTime or you can use the HTML5 feature of YouTube, which does not use Flash to play videos, but you have to have a HTML5 capable browser like Safari 4.

Also have a look at MRoogle, as this issue comes up every once in a while (once a week I seem to remember).
