I have not yet put disc inside, it's coming. USB keys or external drives connected. It works perfectly and reads all formats except divx but there way to modify them easily if needed. The ideal remains MKV 2D or 3D with multichannel sound. The tape management and its subtitles is perfect. If you do not intend to drive inside, no need to take this model, the 600 will do, it's the same electronics. Very good product, no regrets.
