I want to download somthing so i click on it to download. It says there are 88# of what i want to download but when i start downloading it it says that i need more sources. Then i click find more sources and it eventually says awaiting sources so i click resume. Then it starts to connect and then just goes back to saying awaiting sourses. Also i am a mac and what codecs are some of the movies made in cause when i download some of the movies and it says quicktime doesnt have the neccisary components to play this. What do i do?
