Everytime I load a new file and SMPlayer is gathering information on the file, the audio and video stops, I can't pause, stop, raise the volume or even change the player position. And many times while it is doing it, it simply stops the player (and usually freezes the computer). It sucks when I'm listening to an audiobook or a complete album or a mixtape or a set. It completely breaks the mood.
This process should be non-blocking. I wouldn't mind not having the information while it is loading, if it didn't blocked the player.
