 Bit rate performance seems to be higher for DD+ in HD-DVD compared to Blue-Ray.
Bit rate performance of at least 3 Mbps on HD DVD and up to 1.7 Mbps on Blu-ray Disc. http://www.dolby.com/promo/HD/ddplus.html |
Unfortunately this is not a selling point for HD DVD. DD+ main benefits lie in encoding at lower bit rates in more channels (i.e. 7.1) While DD+ at 640kbps sounds more open and airy than DD at 448kp, the differences between 640kbps and 1.5mbps+ becomes much more subtle.
The Bluray group has said on many occasions that they are more interested in the new lossless formats than they are in the new lossy ones.
