There's a ruckus being started about how Warner is producing discs for both BR and HD and not optimizing the disc for each format meaning they are encoding the movie and such but limiting themselves to the size of a HD DVD 30 gig disc meaning 20 gigs of space is being unused on the BR disc. The current argument is that the low bitrate vc1 encode that Warner has done for Blood Diamond is an issue and looks quite poor on the BR version thus far. HT Spot did a review http://www.hometheaterspot.com/fusionbb/showtopic.php?tid/137411/post/new/#NEW Quote from the reviewer: The others that are producing these films like Paramount is doing a different encode for each format. While I can't complain they used an uncompressed audio track and didn't screw the BR owners on the audio, I got to wonder if this is a bigger issue that needs to be addressed by Warner. It'll be quite interesting to see if it's just a poor encode for both formats or not.
