The DD+ signal will not pass via optical or coaxial....so it downgrades it to hi bit tate DTS....or at least your gear reads it as DTS...which is 15 db down on Warner titles.
Only Analog or Hdmi can handle the bandwidth of the DD+ signal.
Hdmi,as well as analog 5.1 on the Toshiba will pass DD+....but to be on the safe side....this player will never decode DTS-HD without downressing it in some form....so the best thing to do for those with patience, is wait for hd dvd and BD players with hdmi 1.3...which will not only decode all codecs, it will offer built in lip sync help also.
I ended up taking the player back to BB.
Its just so slow at loading and everything else..it will re-start the movie after pushing anything other than pause,it never remembers were you left off in the movie, I have had a dark blue screen instead of the movie a few times, as well as hdmi error codes.
Others have had the player freeze during playback, but mine only frooze while trying to start a disc a couple of times.
It took the manager at BB 3.5-4 minutes to get the hd dvd disc out of the player that I forgot after plugging it in, which I thought was ironic because he mentioned he thought these new players were rediculously slow just before this.
Also its far more sensitive to hum using analog cables than any player I have ever tried.
To some the picture as well as improved audio via analog or hdmi is worth the quirks....but I will wait for Blu Ray, and maybe buy another hd dvd player down the road when the quirks are worked out.
