Delay Compensation Woes

[onesockshort]

I am having some trouble with PT12 and using delay compensation when mixing and printing(destructive punch) all within the same session.

Searches on this forum presented solutions to most of the problems. All of my record tracks I have disabled the low latency monitoring. (Ctrl-Command-click the track compensation indicator in the mix window)

Now that I printed and am QCing things I am seeing a new problem.

My units bus and route to various stems. Those stems bus to a 5.1 Printmaster and are double bussed to 5.1 > 2.0 fold downs using dolby surcode. This gives us our stereo dialog, music, and fx stems.

The 2.0 crash downs are bussed to an output.

The 5.1 Printmaster is routed to our monitor system and also double bussed to a 5.1>2.0 fold down.

All of the stems delay compensate correctly and match the units.
The 5.1 print master compensates correctly, matching stems and units.
The 2.0 print master compensates correctly and matches.

The FX Crashdown, which is comprised of FX(5.1), Foley(LCR), and group(5.0) all crash down and compensate correctly - matching up to the stems and units.

The MX Crashdown, which is comprised of only the 5.1 Music folded down compensates correctly.

The Dialog Crashdown, which is comprised of 3 mono dialog stems and a 5.0 dialog stem, is where funky things are happening and not correctly compensating.

The entire DX crash down does not properly compensate. I can quickly tell by where my head and tail pops are. Easy fix if it was a global difference, but even within it, the DX A, B, C and D stems are not hitting the crash at the correct time. So if I slip it to match my DX A stem, it matches my B stem but does not match my C or D stem.

What is odd, is that they are hitting the 5.1 print master correctly, but not the 2nd bus that they are being sent to, which is where that fold down happens.
