HI GUYS

Hi all I have a 55" lg tv so I treated my self to the LG BH743OP surround sound system as I thought they would look good together . Now I connected my TiVo box to the surround sound via hdmi lead and the digital optical lead from TiVo to surround sound , then from the surround sound I connected it to tv via hdmi lead and all worked superb , now over the last few weeks the surround sound system keeps freezing then turning it self off arrrggghh so I contacted LG who said try to connect both TiVo and surround sound separately to tv via hdmi leads and use the optical to connect from tv to surround sound. So did has help centre said and the sound quality is loads better but its still the same have tried new batteries in remote and new optical lead am I doing something wrong with the set up has the LG advisor said was in the first place or is LG surround sound faulty . Has anyone else had any similar problems

many thanks
