Hi guys, I've got a weird but VERY annoying and pretty frequent problem with Sky Digital. Whenever there is a scene on some digital channels (mostly E4) which have a lot of white in them (for example a shot of an overcast sky or a white backdrop behind a person) my pciture shows signs of artefacts from the signal and the sound makes a sharp "scrtttch" kind of noise and my tv volume goes right down and slowly turns up again on its own. Its happening more and more frequently and sometimes makes things in-audible and sometimes even un-watchable. I have a Sony 32" trinitron TV and a panasonic sky digital box. HEEEEEEEEEEEEEEEEELP!
