I don't want to send my Samsung HW-E450 back to Amazon because the sound is great and it fits our room requirements perfectly. However, I've posted here several times about the system's inability to sync the video and audio. I've tried all different settings with the Soundbar remote (i.e. Smart Volume on/off, Sound effects on/off, Sync up 25ms, 50ms, etc. Moving up toward 100ms makes it worse). On some occasions its almost on the mark and in others there is this infernal delay. I've talked to Samsung and they had no advice other than what I've tried and to pull plug power off and on. That seemed to work OK for a while, then back to the delay while watching a cable movie. Its disconcerting listening to the news and watching/hearing this delay while the newspeople are moving their lips! I have an optical digital cable running from the Soundbar to my Samsung HDTV (LN-S4041D). Is there another suggestion for a hookup that might solve this problem?
