I had an movie collection stored on a shared windows hard drive. I recently bought a new LG smart TV and immediately strange things would occur. Movies that worked once fine now would lack audio on playback. Then finally a film played back with the directors cut dubbed in. There was still only one audio track. Just not the movies original. Upon inspection I discovered that a bunch of movies all of which now had audio issues, were no longer the sub 2gb size as originally but rather 8 or 10 gig. I ran all the anti-virus software I could and found nothing. So I wiped the operating system and rebuilt the pc as a Linux box. Now when I inspected the hard drive I found a hidden file that opened up a folder named LG and within were a bunch of encrypted and unencrypted files and images referring to my movie collection. The consumer is no longer sacred and respected but sold out at every opportunity. This is my warning. But I'm not tech savvy enough to offer more specifics.
