Getting more frequent over time: never, ... once, one month later, a few weeks later, a couple of weeks later, a week later, now twice a week or more. 5> Are you restarting from the menu or by unplugging? from the menu 6> If youve ever been present to see the video switch from fluid to static, please include as many details as possible about what was going on. Usually, it's when I sit down to play saved programming, and the problem is immediately evident. Video runs for a second, then a few stop frames, then freezes. Video failure is very similar to a bad DVD. Audio continues for a short while, then often freezes as well. Restart the DVR, and the same recorded material plays fine. Theorizing here, the short-term symptoms seem like "core cancer", as it's fixed by a re-boot. However, since the problem didn't happen for the first several months, that sounds more like a fragmented hard drive or database.
