I went to see Blade II last night at my local Odeon (good fight scenes & a lot of blood but not much else). What surprised me however that the film soundtrack was played in a format called "Sony Dynamic Digital Sound" (there was a demo trailer shown before the film started) instead of the usual Dolby Digital or the odd occasion DTS. I have seen this format advertised on some film soundtracks but I have not watched a film at a cinema played with this sound format before. Can anyone please explain how many channels this format has and is it any better than Dolby Digital or DTS? Will it catch on as a soundtrack format used in home cinema & DVD? In my opinion it didn't sound any different, simply because it was too loud for my taste!
