I'd like to know how to turn off the LED. The slow blinking is kind of annoying at night when I've got it plugged in at home!

I have used pieces of shrink-tubing around the LED on my player to reduce its perceived size. My Mk1 player is now a home player mounted near my television set, and I have reduced the visible part of the LED to a mere pinpoint so that it doesn't distract us when we watch a movie.
