How can i make it appear as two of me in the same room (clone) by merging 2 videos i have avs and roxio 2009?

You'll need to shoot yourself twice, in the same space, using the same camera LOCKED OFF in a single shot. The key is to NOT cross an imaginary "center line" running down the middle of your image. Then you need to crop and align the two clips in editing. Also, try to avoid any elements in the background that might cross that middle line (where the two clips will be "seamlessly" joined), like trees blowing, people in the distance, cars ping, etc.
