Hi guys,
So, as far as i can see, the problem still remains and as others mentioned, it's not only one problem (the one with the subtitles).
So to conclude everything here, so far the problems are:
1) Subtitles doesn't play as they have to.
2) The menu is too slow
3) To open the menu you have to push a button such as "smart" or "guide", "info" etc, wait for few seconds until you see the message "System Manager Initializing" (or something like that) and then you can finaly enter the menu.
4) The above includes the problem with the "guide", that you cannot enter straight after you turn on the TV and you have to do what i wrote before.
5) For a strange reason, when i (finaly) enter the LG store and try to download an app, it always asks me for my e-mail and password. That means that it doesn't keep my details in memory and i have to do it every time i'm trying to download an app.
6)A very big problem that i found yesterday is that, through the TV's browser i cannot see any flash video. It says that Flash is not supported. WHAT???
Guys, if you have anything else to put, do it because i'm looking to send the link of this thread to LG.
