scart hd problem

[jimmynewbie]

when I attach a/v sender to the scart socket the picture received on my bedroom tv is frozen .The pictures on sd are ok . Any ideas on why

[seamouse]

some boxes when put in HD mode cuts off any signal to the scart and rf. I know virgin boxes used to do this

as was as you cant watch HD via scart.
