Trying to record Stereo Mix with a monitor through my headphones. Using Screenium to record Audio and Video, using Avid MBox Mini with MXL 909 Microphone for the audio through the interface.

Basically, what I am trying to do is this:

Record my screen through Screeenium, record my voice as audio through an Avid MBox Mini (interface) with a MXL 909 microphone to pick up the audio. I have all that figured out. I'm able to efficiently record my audio and screenplay through these instruments and programs. What I am having trouble with is the stereo mix. I am running into a slew of problems here... My goal: Add on the audio of a game that I am playing (for example, Amneisia) so that the audio for my game will be picked up internally, and not through the speakers to be recorded through the microphone. I want there to be no external sound except me talking into my microphone. I also want to be able to HEAR the audio of the game through my headphones (and if possible, myself as well, through a monitor maybe?)

Problems I have run into so far:

-Haven't gotten it to pick up in game audio at all while using headphone. Can't figure this out

-Downloaded soundflower, have the output as soundflower. Not picking up anything, will put all my sound and midi settings at the end.

-When I do record through my microphone, it is only picking up a single channel (left earpiece only, no right channel)

-I have figured out it is NOT the equipment, I use Pro Tools and am able to pick up both channels with my mic, recorded a few tests. It's settings and I can't figure it out

-Trying not to run 16 million programs while running the game, will cause lag.

Summed up:

Trying to record:

-Audio from gameplay of any game I am playing through alternative route of speakers (do NOT want to record game audio through speakers, internally)

-Record voice through Avid MBox Mini and MXL 909 microphone.

-Record screen gameplay through Screenium

I followed a guide that told me to achieve "stereo mix'' I need to download soundflower and follow "X" steps. That is done and these are my current settings:

Audio Midi Setup - Stereo Mix custom Aggregate Device, Soundflower (2ch) selected, Avid Mbox Mini selected, Soundflower Output #1 has 2 channels (1-2), using Avid MBox mini for "Input" in order to record. Using Soundflower AND Avid MBox mini as "Output" in order to hear the sounds and replay game sounds (could be the problem? Maybe?)

Sound Settings - Output Stereo Mix (custom channel) Input Avid MBox Mini (recording)

I'm hoping this isn't too hard to understand.. I'm VERY bad at explaining information regarding computers.. It's hard becuase I don't understand it. I can clarify anything that I am able to, so any help on finding certain things would be greatly appreciated.

My computer: Macbook Pro MAC OS X Lion (11G63) 10.7.5 2.4 GHz Intel Core i7 4GB 13333 MGz DDR3 (If any of this is imporant)
