For me YouTube has gotten worse and worse for the last past months. It buffers really slow (I have ~50 Mbit/s so I should be more than fine), errors that occurs (A 10 minute video can stop at 1:23 and think it's done).
Is there anything I can do to make this better? I'm using Google Chrome (27.0.1453.93) on OSX 10.8.3.
