Notes about the XMPSES file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The XMPSES file type is primarily associated with 'Premiere Elements' by Adobe Systems Incorporated. Premiere Elements is a DVD burning program. The video is in an .M2V file and all of the DVD marker information (chapters, scenes, etc.) are in the .XMPSES file in the same folder as the .M2V file.
