I have an iBook G4 running OS X 10.4.11 and I really would like to watch youtube videos, but it is very choppy and generally impossible to watch!
I've read over this thread: http://forums.macrumors.com/showthread.php?t=768766 and it suggests changing the power to Best Performance, turning off hardware acceleration, and upping the Flash cache size to 10MB, all of which I have done. I'm also downloading the iBook optimized Firefox 4.0 to try that out (though that seems a little outdated, seeing as the newest version is about 20 versions newer.)
Strangely enough, my system can play DVDs at full-screen with no problem whatsoever.
Does anyone know of any good, lightweight, web browsers (or alternatively, a way that I can get Youtube working within TenFourFox 24?)
EDIT: Just a heads up, I was able to get 240p playing fine in OmniWeb. Version 5 I believe. It had occasional lag, but generally it was good. My internet isn't good enough to play anything about 360p, so I don't go above that, but I really would like to be able to use 360p instead of 240p, if possible. I think it's the quality of the video that is causing the lag, even though DVDs play at very good quality.
I also tried using the optimized version for iBook G4, but it said that it couldn't run on my system...annoying.
