Ok, so here is a question. I know my G5 is an aged girl (1.6GHZ) but I dont understand why she plays YouTube videos choppy. I mean my iPhone freaking plays them better. The odd part is, that this is really limited to YouTube...Other type video sites, once loaded, no problem so Its not my internet speed, I have a 10MBS line for the house. So ill wait for the entire video to load and not even on the HD format of YouTube and after that, you click play and it stutters or the audio will be fine but video will lag. As far as computer specs go 1.6GHZ 4GB Ram Radeon 9600Pro 10.5.7 (.8 later today lol) Any ideas as to why?
