Edit: Three weeks after purchase. Had to send the unit back as it can only be partially operated with my TV. Each film was a challenge, whether it is the unit itself, I do not know, for me, it was a bad buy. Teste now another Soundbar LG.
Edit from 10.10.2014: LG Soundbar runs flawlessly. Whether I had saved a defective item or device only at the wrong end I do not know. Fact is, now I have a great sound without operating problems.
