Hi, I recently acquired an iBook G4 that seems to handle almost everything I throw at it very well. Web browsing and DVDs and even some older games zip by at a very nice speed. There's one big deal though, YouTube is almost unwatchable on it. For a 5 year old computer this shouldn't happen - YouTube came out in '05 after all. Videos are very jerky and it's quite annoying! I am running Flash 9 and Safari 3 as well as Tiger. The machine clocks in at 1.33Ghz with 1GB of RAM. Can anyone advise me on how to make them more watchable?
