DMR-XW480 DVD recorder/player keeps turning on my tv by itself



I don’t know if this is supposed to happen but … My DMR is connected to the TV via HDMI cable When It is recording [ one or both tuners ] and I am watching ONE of the programs being recorded - I turn OFF the tv to go to bed and let the DMR carry on. A few seconds later, the DMR turns my TV back on saying it is recording that channel and do I want to stop recording [ ???]. It refuses to let me turn the TV off if I am watching one of the channels being recorded. I thought the DMR was totally independent of the TV tuner and what the hell has the TV got to do with the recorded signal from it’s own tuners ???. It certain does NOT turn the TV on when it starts recording with the TV off to begin with. This beats the crap out of me and I can’t find any reference to this behaviour in the book.
