I just bought the new macbook (2.0Ghz, white) and Im have to say that i am very happy with it. (Oh, im a convert). BUt there is just one thing thats been bothering me. My videos (.avi) arent playing on quicktime. I dont know what the problem is. The DVD player is working, i checked that, but when it comes to .avi videos nothing happens, the quicktime window stays white, although i can see the marker moving ( which means that the video is playing). I tried downloading divx for mac ( to get video codecs and stuff) but it still doesnt work....can anyone help me?
