Using RC4 I indexed a transport stream, with Timestamps enabled. The first part of the output says:
Code:
DGIndex Timestamps Dump

frame rate = 29.970030
V PTS 4056924629 [45076940ms]
V DTS 4056917121 [45076856ms]
Decode picture: temporal reference 831[I]
 A0 PTS 4056881918 [45076465ms]
PCR 1217062932236 [45076404ms]
I subtract the (converted) 'A0 PTS' from the 'V PTS'
45076465 - 45076940 = -475
which matches the delay in the ac3 filename.

I then did an 'Analyze Sync->Track 1' and gave it this timestamp file. The first part of the output says:
Code:
Delay Analysis Output (Track 1)

Decode picture: temporal reference 831[I]
delay = 27252
Decode picture: temporal reference 845[I]
delay = 27711
Decode picture: temporal reference 859[I]
delay = 28170
Decode picture: temporal reference 873[I]
delay = 28630
Decode picture: temporal reference 887[I]
delay = 29122
Decode picture: temporal reference 901[I]
delay = 29581
Decode picture: temporal reference 915[I]
delay = 30040
Decode picture: temporal reference 929[I]
delay = 30499
Decode picture: temporal reference 943[I]
delay = 30990
Decode picture: temporal reference 957[I]
delay = 31449
Decode picture: temporal reference 971[I]
delay = 31909
Decode picture: temporal reference 985[I]
delay = 32368
Decode picture: temporal reference 999[I]
delay = 32859
Decode picture: temporal reference 1013[I]
delay = 33318
Decode picture: temporal reference 3[I]
delay = -390
Decode picture: temporal reference 17[I]
delay = 69
which I can't make any sense out of, given the description of this function in the docs. In particular, I would expect the first 'delay =' line to be either "-475" or "-42711".

Am I misunderstanding the docs, or is there a numerical rollover occuring in your calculations?

Thanks!

EDIT: PS - RC4 is giving me identical 'field transition' and AC3 output files from 'Save Project' with or without Timestamps enabled. (Thanks!) However, 'Demux Audio only' is still producing bad AC3 output file.
