Notes about the DVR 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 DVR file type is primarily associated with 'Media Center' by Microsoft Corporation. In Microsoft Windows XP Media Center Edition, Microsoft has introduced the *.DVR-MS (DVR) file format. Similar in format to *.ASF, the *.DVR-MS (DVR) file enhancements allow the creation of key PVR functionality, including time-shifting, live pause, and simultaneous record and playback.
