I have this soundbar home cinema/ blu ray system since 2009. never been used much other than as home cinema, now i tried a Blu ray disc but only get the answer: disc unknown. it simply does not recognize the blu ray discs anymore, official one no copies. Anybody an idea what could be wrong? i am gong to try a software update since it may be long overdue but not sure if that would cure it. Any suggestions are more than welcome. thanks rolf
