I have the Power Timer set to power on to BBC1 HD at 08.15h and off at 08.55h daily with a low volume setting. Until this week this has always worked as it should.

The last few days however, the box has been switching to BBC1 HD while I am watching a recording at 20.15h and the volume dips down to the low setting.

I have checked the settings and they still say Power On at 08.15h etc. TV Guide is also showing the correct time in the top right corner. I probably just need to switch the box off at the wall for a few minutes but has anyone else experienced this issue?
