Spin up the harddrive when unpause media.
When un-pausing media that has been paused, playback buffer remains in memory and the video or music will continue to play normally for several seconds, until it suddenly stops and waits for the media hard disk to spin back up so it can read more data into the buffer.
Please spin up the hard disk and buffer data upon un-pausing the video or music so that its playback is not interrupted by last minute spin up.
