Hello, I have same problems. Also, it has begun to freeze while replaying recordings (this last seems to indicate that I may need a new STB) However, I'm first going to try the total reinstall as at digital switchover time. This has worked in the past to speed things up. There are good instructions for this at digitaluk and digitalspy.co.uk. The key seems to be to first delete all the current channels. Good luck. (I think you will lose all your recording schedule, but not your recorded programmes)
