I was very surprised by the power of such a small card. It decodes well as 720p 1080p. I had some audio problems early. The problem was a bad configuration of the card. Remember to decode the audio in hardware and not software. The most known video players allow you to change this configuration.
This device allowed me to have a luxury Media Center that switches itself on when I turn on my TV, which is directly connected to my external hard drive and 2TB I can control it all from my tablet. It's just perfect!
