Hi, have an emac G4 700 MHz 1 GB of RAM running 10.4.11, use it for internet, music, very little photography with iphoto 2 and occasional writing and by the way it can't do more than one thing at a time. News, weather, you tube any kind of video it is getting so slow, video and sound never match up. Is there anything that can be done to this mainly for video because I can deal with the other things well most of the other things photography is the pits but there is eventually a picture on the screen. Are there adjustments that can be made anywhere to make this last a little longer?
