How's this for corporate fixing? I recently tried to get a quotation for HDAD replication (remember HDAD stands for "Hybrid DVD-Audio Disc", and has a Video_TS on one side with Audio content at 24/96, and an Audio_TS on the other side, with audio content at 24/192. Both sides are High Resolution stereo output) 1. Sony said that HDAD is "not available in the UK" , is not supported by Sony and is only available from Warner in the USA. I checked with one large replication factory in the UK and they confirmed that they did not have HDAD format available nor could they suggest any other factory. I have checked with a third, who cannot understand the attitude - and think the only possible answer might be some form of licensing issue. They will, however, take on a DVD10, DVD9 or DVD5 authored to DVD-Audio/Video specs - which naturally means linking into the Video_TS from the AMG to keep in spec. HDAD seems to be a way around this, with placing each type of disc on a different physical side. 2.Sony said that the DVD-Audio Disc on one side and DVD-Video on the other would be handled by developments in Blue Ray technology scheduled to be released later this year. At the moment, they (Sony Europe) had only one title in this format and that further releases would also depend on Playstation 3 developments - another words - watch this space. 3.The question of difference between HDAD and DVD10 was not raised in this conversation with Sony. In any case, any credible answer can only be confirmed by speaking with Warner. Next call is to Warner USA, and watch this space. But how about that for an attitude from Sony Europe!
