Many Thanks!
problem solved!
Aspect ratio set through my Humax 1000s was set at 16.9.
Checked my LG TV settings using my LG remote control and my LG TV was set at Cinema now i have changed Aspect ratios to:
LG TV: is set to 16.9 (instead of cinema)
Humax Settings: is set to 16.9
This solved the problem of cropping the top and bottom of tv display.
Seems strange to me as even though the TV was always set to cinema i never lost details of time and score on top of tv when rugby matches were being played or tabs on bottom of the screen on the tv when cinema was set using my sky box, Talk Talk You View box only Humax is the first box being affected which cropped top and bottom of the screen.
Many Thanks for all your replies !
