How to record my voice on ps3/dazzle?

hello, me and my friends want to start up a youtube series. We want to be able to do live commentaries, but are having a few problems. We use the PlayStation 3, a dazzle DVC100 with pinnacle studios 12 to record, and turtle beach ear force px21 headsets to communicate. the problem is getting to hear both my voice and our friends' voices on the recording. Basically, if you play call of duty black ops, you know there is a chat thing while you play the game. if you have the headphones on, you cannot hear anybody's voice through the television. We found one way to hear our friends' voices on the recording and through the television, but not mine. The sound needs to come through the television to be recorded with the dazzle (at least that is what I believe.) Is there a way I can fix this without doing a voice over on the computer. Please answer as soon as possible. Thanks.
