 I have written an application that takes several AVI files, converts them
 to MPG, concatenates them together and then converts them to MP4. The AVI
 files are being created as recordings from a Foscam 9128.

 The process creates the MPG files and are playable in VLC. However, the
 first frame is not correct. It is very distorted. The AVI file does not
 appear to have the same issue.

 I am running this on a Windows 7 Professional system. I've included the
 output which repeats the Non-Existing PPS error over and over. Any help
 would be appreciated. Thanks.
