The size of your video is dependent on your screen resolution and the settings of your viewer program (probably Windows Media Player).  The higher your screen resolution, the smaller your video will be.  To view your video as large as possible, you should reduce your screen resolution to 640 X 480.  If you're not sure how to do that, don't worry, its simple!

First of all, you will need to minimize this window so you can see your desktop, which is the first screen you see when you start your computer and Windows opens.  Its also where all those icons like My Computer, My Documents and Recycle Bin are located.  Just click the middle box in the upper right corner of your screen.  That should make this window smaller and allow you to see your desktop and still read these instructions.  If you have other windows open, you will need to close them.

Once you can see your desktop, put your cursor anywhere on the desktop (except over an icon) and right click your mouse one time.  A box will open and you will see Properties at the bottom of the box.  Left click one time on Properties and then select the settings tab.  Toward the bottom of the settings window, you will see a Screen Area box with a slider control.  Place you cursor on the slider and hold down your left mouse button and slide the control to the left (less) side of the box until it says 640 by 480 pixels.  Then left click the apply button.  From there, simply select OK in any boxes that open until your screen size changes.

If you are using the Windows Media Player to view your video, select view and then zoom from the menu bar at the top.  Then select 200%.  That will be the maximum size that you can view your video without major pixelation (distortion) of your video.  Go ahead and try full screen, you will see what I mean.

If you are using the RealPlayer G2 viewer or any other viewer, they all have similar menu selections.  Just experiment around with them until you find the setting you like best.

To change your screen resolution back to its orginal size, just follow the same instructions.
