I was like I want to use mirillis I love it I don't want to use other kind of software but the I tried FRAPS, I've put.
Don't record WIN7 SOUND
RECORD EXTERNAL INPUT -Stereo MIX (ASUS xonar D2 Audio device)-

Forget what it says about the Microphone Asus xonar CURRENTLY unavailable is just because is going trough the Stereo MIX, but in FRAPS it works perfectly is just a problem of my sound card, but if you could just do like FRAPS be able to record an external sound device I'd be perfect.
CONGRATULATIONS AGAIN FOR YOUR AMAZING SOFTWARE.
