I need to reply to this last one just to clearify something. No offend and thank you for help, but if problem was so simple that Internet speed is the problem I probably won't get so much attention to this and register on forum and ask people for help. Those simple answers should be in post scriptum after real solution offered. It saves time on both sides.
Like, hey guys, I have no sound playing my video and someone says: "Press the mute button! It should work after that!" Heureka, Columbo!
I mean, are those guys serious or what? I know there are a lot of problem solutions simple as that but just in case, put those in POST SCRIPTUM if you have to, please!
