Video Skip Patch
Famous Wing Commander editor HCl has developed a patch that fixes the skipping video in Wing Commander Prophecy. Although it's a simple matter to adjust the sound card hardware acceleration, some people dislike this method. This alternative fix allows you to keep your acceleration turned up to its normal level and run Prophecy smoothly.
Download the patch at the bottom, and unzip it to the directory where WCP is installed. Then run Prophecy as usual. This patch co-exists quite nicely with the WCP High-Res patch, if you already have it installed. However, if you install the WCP High-res patch afterwards, you will have to re-install this patch, as a DLL will be overwritten.
