I just got a 33 inch Thomson TV with Virtual dolby. I have a DVD with a Dolby 5.1 and DTS decoder, connected to a 5.1 amplifier speaker system. Unfortunately, I don't have a prologic decoder, so I can only get surround sound from the DVD. If anyone knows where you can get a seperate decoder, I would like to know. However, I was intrigued by the Virtual sound on the TV. When watching from about 15 ft (a respectable viewing distance for this set) I noticed the stereo seperation appeared to be the width of the room, even though the speakers are only about 18 inches apart. I then tried watching a film from about 6 or 7 feet. Now I could hear sounds 90 degrees to the left and right of me and on occasion from behind. I had read that Virtual Dolby is little different from normal NICAM stereo, so I wasn't expecting anything. I suspect that it depends on how it is set up, possibly depending on reflected sound. Whilst not as good as 5.1, it certainly gives a more immersive sound experience than NICAM alone.
