PowerDVD UltraWide Fix
Older verisons of PowerDVD were not able to stretch the movie to fill an ultra wide screen with 21:9 aspect ratio. This application was created to workaround the problem by changing the size of the video renderer window to fill the entire screen. Designed for PowerDVD 11, but it might work with other versions as well. Originally this project was published on Codeplex.
Installation

Usage
