(adsbygoogle = window.adsbygoogle || []).push({}); So I am planning to get the PX21 for my HD PVR.

1. I need a step by step guide on how to set it up! (For PS3)
2. Can I use it while recording my gameplay and gameplay audio, or do I have to unplug it?
3. How do I record my voice (Live commentaries)
4. Can I use to record other people's voices?
