I have a question for you, do you know where i can find the license agreement for the editing software so i can monitize my videos, im sure you will come across the same problem at some point with youtube wanting permission for you to use the video wave software that comes with the roxio game capture hd pro.
here is a link to my youtube channel if you want to check out the quality i got on my most recent upload, with the hd pro
