I was able to get Skyfire working by using a utility called Tweaks2k.net (
http://www.tweaks2k2.com/) Load up the programs and under System Tweaks, you will see an option called VGA Brute Force. Use the folder button to find where you have Skyfire installed (Mine was on Internal Storage/Program Files/Skyfire/Skyfire.exe) Once you do this click the button below to enable, or again to disable VGA Brute Force for Skyfire. Once this is done you will get Skyfire to work Full Screen, but it will not be VGA Quality(it will still be scaling the video.)
Option 2:
Just unzip and copy the file 'Skyfire.exe.0409.MUI' to your Skyfire Folder. Done!!!
