Yes all my apologies, I totally forgot what you wrote before. :S This solved the problem with recording the video & audio screen. The value for canal 1 was very low, what does explain eveyrthing, when I chose Mono on canal the sound was poor, then when I chose Canal 2 on Mono, the sound was normal. I'll try tomorow to record with my drum kit and will let you know if this works too. But it's quite like you've already solved the problem.
