Thanks, i did that and it has worked, it now doesn't shut down but i have lost my patience with it, it seems to miss recordings occasionally and recent retunes have left channels out of place and and the only fix is a factory reset, this means me having to put all the recording schedule back in every time I do this (a total pain in the ****)
I bought another freeview twin tuner with inbuilt upscaling that connects via HDMI, the difference in picture quality is amazing and is as good as viewing SD on to my Foxsat box.
