The DVD / CD he reads quite fast and except for a brief drive noise at the beginning, when you insert a new medium, you can hear almost nothing from the player. He plays everything from well-behaved. Network I have indeed connected but except for updating I use Internet and network almost exclusively on the TV. Crash I have not brought him. But as I said I need less network while Blu-ray player, it will play properly if 3D, 2D or CD, and he does very well and at the price.
