I've been meaning to look into FRAPS for my pc, (my old mac uses Snapz which doesn't capture sound). I like the idea of capturing sound effects and adding your own music ("Ride of the Valkyrie" anyone?).
Another 2 cents - as a long time player I like watching your battle management of power, capacitor settings, etc., but the tactical demo for noobs doesn't cover that. Instead of recording a game "live," you could use the film room as playback to record - that'll slide the MFD off screen and give you that side of the image to type out the tactical notes. Just a thought.
