Oooo, I'm cross. My 433HDE media box was sporadically failing to switch input automatically and was ignoring the WSS signal. Teletext also wouldn't work. I finally got the media box exchanged and three weeks later, the new one's doing the same thing. My old box was in a stack of components so I thought overheating might have caused it, but the new one's been sitting off to one side. Has anyone else had this problem? I remember when I first reported it, someone else said they'd had the same problem. I wonder how common it is though?
