Well at least you guys on the East Coast weren't shut off during prime time.  I'm out here on the west and I worked til 6:30 last night. I had my dvr set to record the Celtics/Knicks preseason game at 4.  I came home, no game, no power, no nothing.  I immediately reset it.  It came back on and started tivoing the post game show.  I shut it off.
About 8:50 , I came back and started watching tv.  At 9:00, it immediately rebooted and started the software download ( screen I never have seen before ).
The only thing that would of saved them from me being upset was if they would've downloaded a software version that allows you to record 2 channels at once without having the 2 lines coming into the receiver (a CSR told me this was going to happen soon, but I have yet to see it.  This was like 5 months ago) .
