Hi, Right now I have a late 2004 iBook G4 with 1.2 Ghz processor, 768 Ram. I have Leopard installed (10.5.8) and just made sure I have software up to date. YouTube is choppy but watchable at 360p, 480p is a no go. However, I want to play a DVDrip 700mb movie with VLC and it's unwatchable, even the sound is stuttering. I was given this iBook, maybe the video card would be somewhat dead.. I wouldn't know. Streaming news sites is ok, everything is pretty much fine, I can even sync my 4S with this thing. Would the RAM be an issue ? I know I can upgrade to 1.25gb but first I want to make sure that everything else is ok. Any thoughts ?
