I use the player for Blu-rays and occasionally to look at pictures from a USB stick. About the Amazon Instant Video function, or its quality, I can therefore say nothing. It's important that a player is quiet - and that's this. When switching on and start the DVD you can hear faint sound duties, which are only to hear when you're in front of the device. Once you move away from the device, you do not notice this. The player starts fast and is preparing neither when playing Blu-rays / DVDs, even when files from a USB stick problems. In addition, the service is super easy, which is a big plus point. You can start directly and without problems.
