After getting a HD DVD player I started to take more of an interest in the software and noticed that alot of titles have a DD+ track. My understanding is that DD+ is lossy & compressed like it's cousin DD, except the compression on DD+ is more efficient & it is capable of a higher bitrate. 3mbps is it's max, or is it 6? But we usually get it at 1.5mbps on HD DVD. If I'm off, please correct me!!!


How good is DD+? And why is it getting so much support? I ask because we are seeing hits like Transformers, Bourne Identity, King Kong, Shrek 3 and so on with a DD+. In certain cases, I'm assuming there just isn't any room for a lossless track like TrueHD, but I doubt this is true of every disc with only a DD+ track.

Why aren't we seeing it at it's full potential of 3 or 6 mbps? Backwards compatibility with existing gear right?
