1098 ground loop

[Glen1]

Hi Guys,
Got a bit of a ground loop buzz with 1098 and 1075. It is a constant volume and only goes away at mute, 0 volume or 1098 off, it's not very loud but there all the same. Volume of buzz does not change at all.
Got two dvd's plugged in via digitial co-axial, cd and set top box via analogue 2 ch and stb and dvd player pictures into 1098 via composite.

Any suggestions?

Unplug your cable/sat feed from the STB for starters..

Tried unplugging aerial plug from set top box - no better.

Try optical instead of digital co-axial on the dvd's. The dvd's also have a ground connection through the video cable.
