1) "'" is shown instead of apostrophe on both USB and DLNA. I tried all changing the code page but it's all the same. This is for English subs, and for other languages special signs are also show with some strange characters.
2) external subs work on USB but on DLNA don't work at all. I read somewhere that external subs didn't work on LG 2013 series, but that they do work on 2014, but now I can't find that source.
I have WD TV Live and used it with previous non-smart samsung and that worked like a charm. I bought lg tv with webos to make things simpler and get rid of many devices and remotes. I hope they will fix this with some update, otherwise I will have to get back to old setup.
@williamsat, what do you mean not that bad? does any of this that i mentioned work for you?
Btw, TV is running on latest software 03.23.17 - 1.2.0-2717.
