Hi,
Having massive signal problems with my virgin TV boxes (one downstairs, one upstairs) - after a certain point in the evening (normally 10:30pm, but sometimes as late as 11:30pm) the picture pixellates and the sound keeps cutting on and off. This fixes itself over night, and stays stable and okay until the next evening at the same time. It's absolutely unwatchable during this time, and is completely unacceptable.

Have reseated all cables, reset both virgin boxes, checked for damage etc. and nothing has helped.
