mine was out for almost exactly 24 hours. acording to the tech I spoke to that is the exact amount of time I would be locked out. I had the L-2 problem, which I was lead to believe all customers with the Scientific Atlanta HDC had. It wouldn't load past L-2, I had access to basic non-digital channels, but not HD, Navigator, or DVR options. The good news is, that even though I was locked out of using these things on my set-top box, my set top box was not locked out of the overall system, so my TV shows like House, ECW, Metalacolypse, Robt Chicken all still recorded as scheduled.
