I am a Japanese music creator. I am going to launch 5.1ch music dedicated label. Sample mpeg2 files are here(5.1ch Dolby Digital Surround Sound) http://sillaguon.jimdo.com/home/english/ This is a Japanese Zen style ambient music. I want to publish DVD that include only 5.1ch music eventually and I want people to enjoy 5.1ch music just the same way they enjoy 2ch music by CD. By the way, does anybody know the diffusive rate of home theatre system in US?
