Increasing the Pause Buffer Within Media Center
the Pause Buffer - The Green Button Community | It looks like someone
figured out all of the registry entries to increase the pause buffer within Media Center. In addition, The Green Button member isomies has created a GUI to allow you to
easily change the value up to 2 hours (default is 30 minutes). I haven't tried it out yet, but download MCE
Buffer Extender and try it out yourself.
Quick Warning: Always backup your system before trying
anything like this.
