I have connected my HTS2511/12 home theatre to my TV using a scart cable. I am unable to play the TV sound through the home theatre speakers since the only options available through the SOURCE button on the remote are OPT IN (Optical), COAX IN (Coaxial) and AUX (Audio). None of these options enables sound from the TV to be relayed to the home theatre 5.1 speakers. I had an earlier model of the home theatre (HTS3180) which had a SCART IN option available through the SOURCE button on the remote to play TV through the home theatre system. Can anyone advise??????
