While watching a movie I had recorded the 5040 shut down, just showing a magenta screen which switched to blue after a while. Is this a common problem for these machines or is this something I should check with SB on. My warranty period is about to expire. I have had this unit reboot just a couple of times on me since I got it back in January but it has never done it before while watching something recorded. Pleasde advise. Thanks, Kyle
