ive got a really strange problem ive had freeview for ages also topup tv for ages but all of a sudden lots of channels have become unwatchable, i cant get any topup tv channels, if i go to analog tv im getting electrically interverance on bbc2&itv, i sent a e-mail to the bbc and there is no problems wth the transmitter which is stockland,ive checked everything there is nothing near the aerial to make the interverance, i work in a tv shop so im quite clued up. any suggestions ive rescanned and done a fresh install but it only picks up 50channels
