Amazing product with an excellent surroound sound. A little difficult to set up if its your first home theatre. Has a very attractive design (especially the blue ray player). The bass is really good. Gives an awesome surround sound for blue ray movies. Optical input is required if you watch channels directly on TV (If your TV is not Sony). DLNA quality is extremely good, though the subtitles do not show up on streaming (one way to oversome this is to use your hard disk or pen drive, in this case the subtitles work fine else you would need to hard code the subtitles) One extremely irritating feature (probably the only con) is that when you watch youtube videos, you cant select the video resolution which basically means that with a internet speed of less than 7 or 8 Mbps (i think)you cant watch HD videos, which is a bummer. The interface is very similar to PS3, so people who have one or have used one, the systems interface will be a cake walk. Plays almost all formats (some formats dont play on streaming but if you use a hard disk or a pen drive it works fine).
