I bought a Philips television with a digital sound output. But then bought a Samsung home theater system used. Only to find that the sound input is optical and that the two are not compatible. I have my television connected with the Anologue left and right sound. This is o/k but only transmits stereo and I get a bit of lip synch. Is it worth changing my HTS to a compatible philips model with digital in. Are there enough television programs with 5.1 surround sound to make it worth it? Would it get rid of the lip Synch? Any help please?
