Just a quick question about the 8742HDC box. According to the quick reference guide, the indicator light on the front panel has a spot for 'HDTV' and '5.1'. These never light up for me even though I'm watching HD channels with Dolby Digital 5.1. 1080i does light up. Should I be concerned? According to my receiver connected via optical audio, it is receiving DD 5.1 and according to my TV connected via HDMI, I am viewing a 1080i picture. I know the light exists on my box as I can see it if I look real close and shine a flashlight at it. I just thought it was odd that it doesn't light up. Thanks.
