Tony, basically, it is the change in dynamic range and the channel structure that is most apparent, not really level. For example, the dts snipe has the flying discs from rear to front, and starts out from a Dolby analog separation and then kicks over to the more distinct multi channel from the dts itself a few seconds in.

I will scour the areas where there were some issues and see if there is just too much leader missing...

Right, so you have to assess whether the delay in switching is caused by wrongly spliced film or SDDS fallback system. Do as Brad suggests.

Well problem solved, after a few hours working with fellow forum member Bernie Anderson. The original setup and installation followed Sonys plans for integration. Well that wasn't the best way it turned out. The 'fallback/hierarchy' architecture added a few seconds to the format changes.
This wasn't how a processor is supposed to work (literature for 6D even said the unit does not work with SDDS). Using the info for the 6D triggering structure, we made some connections for the SDDS automation plug. Viola! it works now. Instant changes.

Congratulations on the solution to your problem.

Would you be willing to diagram the solution so we all can see it and Brad can post it in the Manuals section?

Only through sharing will this site work as intended.

Sure, no problem. Just give me a few days to find a quiet time to do so.

Great. Thank you.

It is in the true spirit of this forum to do so.

All we did was set it up to pulse format change via automation plug (like any other DTS setup)

DTS Automation Output----------> SDDS Automation Input
13- Out Common ----------------> 14 Common
11- Out SR --------------------> 5- Preset 5 (SR)
12- Out Non-Sync --------------> 6- Preset 6 (NS)
25- Out DTS -------------------> 7- Preset 7 (DTS)

Works perfectly with out any lag in changeover to DTS

It looks like Bernie was referencing an early draft of the solution. This is what the final cable turned out to be:

Since I am having trouble posting a table, hopefully this formatting will help:

DTS 6D UNIT- DB 25...wired to...DFP 3000 – SDDS 37 PIN
Pin 12 – Logic Non-Sync...to... Pin 5 PRE2 – Non/Sync
Pin 23 – Logic A....... to......Pin 7 PRE4 - Dolby A (NR1)
Pin 11 – Logic SR...... to......Pin 8 PRE5 – Dolby SR (NR2)
PIN 25 – Logic DTS..... to......Pin 9 PRE6 – DTS (AUX1)
PIN 13 – Logic Common.. to......Pin 14 Logic Common
