I've a collection of .mp4 encoded files but how can I get my media center to list those files? I've tried to add a registry key I've found in the internet but it is working only until the next reboot or shutdown? How can I add this permanently so that my media center list those files? My key looks like this:
Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\.mp4] @="mp4_auto_file" "PerceivedType"="Video"
