I have a power mac g4 running 10.5.8. it has a 867 mhz processor and 1gb of ram. I recently just did the update from 10.3 to 10.5 everything is working great except for youtube. I will watch a video and it will play the audio normally, but the video will either skip, or not load. I Have tried youtube in firefox and safari. videos work in only 240p which looks horrible. other than that NOTHING will work. please help?!
