I'm just curious if it's every night or just every so often. The reason I ask is because I've had 2 occasions in the past couple weeks where I was scheduled to record something at 1am and both of these particular shows started to play back and the picture freezes about 1-2 minutes in and will not play any further. I assume it's because the system shut down for a software update or maybe was just checking for an update (I'm always asleep at this time). But I've also had other shows that I've recorded at 1am and never had any problems. So I'm sort of worried about recording anything at 1am anymore.
