I use Fraps to capture action for the best quality but it will eat up a lot of resources. You can use the aces high film viewer and record every flight but that uses resources also. AH film viewer may be the best because if the action does not workout...just delete it.
Then I take the Fraps and edit it in windows movie maker to post on you tube or emails.
Fraps is free for the 30 sec version @. Www.Fraps.com
