From internet:
I had the same problem, My LG did not even recognize the .m2ts file. So I simply renamed the .m2ts to .mkv and to my surprise it woked! It should not have but it did and played the movie no problem ^^.

Hi George
my self krishna from india. lg webos better than another os like android or tizen because both are os not secured but saurabh don't know. android not make sony, micromax, llyod android os is google os. and not safe if he using android phone he know very well.that he open or download any app from playstore or web page auto mode create a junk file in your file manager and this is not a file this a virus. so this is not safe for your tv.
Flash is unlikely to ever be supported by LG, it is a terrible fast fading technology better to badger sites that use it to upgrade to more modern technology. As for more apps there is a link on this site that will take you to LG's suggestions page where you can ask for specific apps to be created.
