while reading the stats on the soon to be available hd dvd player i noticed it said 7.1 dolby digital..now my reciever is 7.1 and my dvd player will be 7.1 ..but we still need these movies to be made in 7.1 right...and if thats the case ..why does this dvd player boast 7.1 when my reciever already has a dolby 7.1 ,,i looked at the toshiba hd player and its says its 5.1 So is there any point to that hd dvd player being 7.1?
