1. Soundflower 16ch.
2. I don’t have any other devices, hence the soundflower.
3. Internal 5400rpm 250GB late 08 MBP.
4. I just discovered that it can play back for 22-28 seconds before it starts to wig out and stop (within two seconds or so). But, I can start that 22-28 sec wherever i like in the video with the same effect. ie. 0-22 sec in the movie will be fine, but so will 15-37sec of the same movie, and my ram is lookin good, WEird and annoying eh?
