If you have a TiVo HD, could I ask of you a favor? When you set the front panel display LED lights to off, does the green power light stay on? For the short time that I had the S2DT, when you set the LED lights to off, ALL of them turn off. However when I set all the LED's to off on the TiVo HD, the green power LED stays on (which is unexpected). If you have a TiVo HD and can please try turning off the LED's (in the display settings) and then report back the result I would greatly appreciate. Thanks!
