Summary: I have a large movie and music and photo collection stored on a ReadyNAS and I hoped to use this usint to play the media through the network onto my TV. My needs are simple so I thought that this unit might be for me. I had no trouble getting the unit set up and working but during playback the unit stutters sporadically and then locks up. The only way to recover is to do a cold start by unplugging the unit.
Summary: Please don't make the big mistake of buying this thing. It has many firmware problems, it doesn't work at all. It has so many absurd things like for example if you want to configure it to see iby HDMI digital cable, when you turn off the device it automatically changes the configuration to analog so you have to change it every time you want to watch a movie. Also, it says that by pressing shift button you can add subtitles to the movies. That is not true also.
Summary: Bought this unit along with the Extreme gigabit wireless router. DSM-510 was DOA. Took it back, and got the second one. It is unable to stream consistent video for more than 10 minutes to a room that is one wall and 15 feet away. Save your money and your time and get something else.
Summary: Like the previous review, I also think that Digital Media is the way of the future. I had high hopes for this device as it support DVR-MS format, except, it does not. Your home PC needs to transcode the DVR-ms files in order for the DSM to work. Said another way - you better have one fast PC. Now to the problems. It looses sound quite often - easy to fix by just turning power off/on, but after the 10th time that gets old.
