I have a commercial DVD (the content of which I own the rights to) and I have an mp3 (which I also own the rights to). Two questions: How can I make another "video" using the visuals from the dvd and the audio from the mp3? Then, how can I turn this final file into an .avi? Further, what if I want to run the DVD's audio track at a diminished volume beneath the audio of the mp3, therefore using the mp3 like a commentary track? I'm on a Mac.
OS X: All of a sudden clicking things on the menu bar of any program makes a SF-like "click" noise. (I checked under sounds in the system preferences and noises from the interface is unchecked.) It happens when I click on the Apple in the top right or the program name and sometimes File. I have not installed any news software. My question is: WTF? [more inside]
