For the last two weeks, my box has had trouble playing back both recordings and delayed live tv. After about 15 minites, it'll freeze for a couple of seconds, and then carry on playing, but not from the point where it froze - it'll jump forward however long it froze. Live tv is ok, which to my mind points to the hard drive - but the web if diagnostics say it's ok, and I've only had it 6 months. I'd expect it to fail instantly or after a few years. I'm on 1.03.12 2.22.
