My 522 is in the bedroom. Every night before I goto bed I unplug it. The reason is the sound of the hard drive keeps me awake. I have been doing this since last summer. I plug it in again in the morning. And everything seems to be fine. My updates are done each evening before I do this. Lately the DVR is more buggy then ever, even with the L233 version of the software. Could this be because of unpluging it? Or is it just the same old bugs that were all used too? Any insight on this would be appreciated.
