This would be interesting to have tracks in different offset, but then sound wouldn't be good as it is, because both are used to get more data stored on film, and we do talk on 2,2MBits/sec which is not so easy to do, on other hand dolby has 320KBits/sec which is I think comparable to 128K mp3 recording (on each channel).
Nice you pointed DCP1000, also great unit and it can be still used for D cinema, and thing that I MOST like on it, when doing some special venue show, festivals and so, you can put it up to 8 AUX input board and 8 projector/non sync board...

quote: Tony Bandiera Jr One would think so, but Sony screwed up big time by doing one major thing wrong: both tracks are in the same time relationship, not offset so if one side is damaged (or at splices/missing frames) you lose the data from BOTH tracks.
Come on Tony...if you are going to slam something, at least get your facts straight. The two tracks are indeed offset from each other! I don't have the offset handy but it is pretty easy to demonstrate. Put a piece of tape across the film (clear) and run the software and run the error test. When the tape runs through, they will not jump at the same time...I believe "P" will jump first. Since both P and S carry the center channel in an uncompressed format, the offset ensures that it takes a dual failure for a protracted period to drop center channel, ever.
While it is fun to put up the different names of SDDS...and they were mostly earned...at its end, it was a reasonably reliable system. Those that we have in operation still are tracking fine. The AFI/Silver, which often runs "previously enjoyed" prints...if they are SDDS can and do run them...with rarely, if ever an SDDS problem. Note, the AFI/Silver has the rare but coveted DFP-D2500s...known in the booth as the "best damn 8-channel VU meter for that is what they mostly do for non-SDDS films).
