I have no idea if this problem exists in other OS:es as I don't run OSX or Linux.
When using the Record option, it always skips the first few seconds. That is, if I start recording at 3:02, the actual recording will start somewhere around 3:05. It's rather unpredictable too, the delay ranges anywhere from 1-3 seconds, so I can't offset the problem by starting to record earlier than I want to. Solution?
There's a similar thread here with no posted solution.
