I have had to shut off my playbar and turn on the crappy TV sound just to watch the movies. Would love if someone has a solution.

One thing you should always do is go in to your TV's audio settings, and make sure that it's set to pass Dolby Digital, of course, but also turn off any extra sound features that the TV may have, all of which will add a certain amount of processing delayto the signal. That probably won't get rid of all of the delay you're hearing, but if you've got one of those extras turned on, turning it off will certainly reduce the issue.
I happen to be a DirecTV user myself, albeit through a Vizio TV. You may want to go in to the audio settings on your DirecTV and make sure that it has Dolby Digital turned on....or maybe you don't....that will cause more lag to appear.
One way you could skip having the TV actually process the audio at all is get one of the external HDMI switches that separate out the optical signal before it goes in the TV. There's a lot of suggestions of those kinds of devices in the Home Theater section of this website, I don't use one myself, so I've got no particular suggestion.
Hope this provides some food for thought.
