Folk have found this to be a problem in many Smart TVs, including Samsung. Fix? Return it as not fit for market or take the plunge to learn encoding and figure out what this TV likes.
Me? I turn it into a TV and use a box like the WDTV. Only those new to Smart TVs think it can be fixed by the maker.

I have lg smart tv 32ln572b. Its video player works good. It run movies from usb but when I run a movie in fast forward and then return to normal speed the movie resume from a little earlier time (from 3 to 10 seconds) instead of resuming from the point where I pressed the Play button.
Any one know about this issue? is there any fixed available?
I also have samsung tv. and same movie runs correct on it. Resuming to normal speed form fast-forward just plays from exactly the point where I pressed Play button.
