I was wondering exactly what this is. My Toshiba DVD player boasts this feature, yet my Yamaha CD player does not. According to Toshiba, there's all these new cd's that are HDCD, yet none of my new, or any of my cd's for that matter claim to be HDCD. So if DVD player 'a' has HDCD and player 'b' doesn't, does one opt for player a?? Thanks.
