I had exactly the same thing happen to me, but different show.
I was watching a football game from NFL sunday ticket. Paused it and put on a VOD kids show for my son. We watched that, and when it was almost over I hit the List button, picked the football game and hit Play. Screen went black. The power light would flash when I hit a button but nothing would happen. Ring was doing the same dim to bright transition thing.
I waited 5 minutes for something to happen, but it was no use. Had to RBR.
The football game was broken into two parts, I think directv breaks the transmission signal on the NFLST games at some point, because all my games end up in two pieces, one with the whole game in it and some filler stuff on the end, and a blank one that seems to fill out the 4:30 period.
After I rebooted, the blank piece was gone, but thank god the rest of the giants/steelers game was still there. So whatever happened, it deleted a show on me as well.
Late last night I hit play on the Browns / Jaguars game that was recorded on Sunday. Box instantly froze. TV reported loss of signal. Only out was the BRS. This is the second time this has happened since 290 came out. The game played fine after restarting the system.
