yes I know its not a Aces High video but if you by chance had Fraps you need a program LIKE AcesHigh for it to record the video of Aces High while you play the video of 300 so that it captures the audio from the video of 300... programs like Aces high, Itunes, Google Earth etc...
If I wanted to take the audio that is what I would do
(while fraps is running)
Open AH2 sit in the tower, than hit the windows key out of the game.
Than open the video of in your case 300.
Click on the AH2 tab to get back into the game click the button to start recording with Fraps (not the alt R button, the button that is set to record with the program Fraps).
Windows button out, press play to play the video of 300.
Quickly click the AH2 tab and sit in the tower until the video is over.
Fraps will have recorded the audio through AH2.
And just take that video of AH2 with the sound you have recorded on it and stick it in the audio section of the film maker. ( the same place you would normally place audio)
But like I said you must have Fraps
