Virgin Engineer came round and straight away knew about Sharp Aquos compatability problems. It's not the cable or the box, although Sharp say "VM HD boxes" are faulty - contact them. Where do I go from here? Do I go back the Comet and tell them that the TV is not suitable for the purpose I bought it for and then get another model? Or stick with a scart connection? VM or Sharp are not Budging, so Im kinda stuck.
