[SOLVED] Won´t play videos from library, but can from files?

[paplo]

Now i just cleaned the library that my Pi had made from my computer and it removed it all. I then rebuild it with my computer and now the Pi won't play anything in movies or in TV Shows, just like then i started.. My conclusion is that if the Pi don't make the library the first time, it wont play anything. If i use the Pi to create the library and then clean it from another device, it removes it all.. There must be a solution to this?
