Thanks Graham, I'm presuming from what you say that if my preferred volume level is the one that is set when making the timer settings then it should preserve my preference which it isn't doing.
From what you are saying re HD channels which mirrors my experience exactly this is a general glitch. This is annoying on a 4 channel timer 2tb box because the whole tendency for this box is to be used for recording more speculatively for more of the day and one doesn't want to be powering on and off to reestablish the non-HD channels. The box feels insufficiently tested with these basic glitches. I cannot say that authoritively because I have no point of genuine beta testing comparison with say the Youview testing where I receive requests from the beta team to try stuff or intended firmware/software beta updates every few weeks or so.
