How many times have we filmed this now?

I took the footage shot yesterday into college this morning and managed to capture it. The quality of footage after keying out the green screen is rather good in the rotating sequence however the walk cycle is only just acceptable. We weren't strict enough with the lighting so the two pieces of footage don't match up completely. I also explained the trouble we had been having with Final Cut to Matt, he suggested changing the audio/visual settings to a non-controllable device. If that doesn't work then it's most probably an issue with Alex's Mac apparently.
