Well, it just might be the DS capture engine, or even something else.
I've had issues with time code breaks on mini-DV tapes playing out of
our Panasonic AJ-SD930. The DS time code position display just keeps
chugging merrily along across the break without displaying the new time
code, which does eventually appear correctly once the deck is stopped.
The trouble there, of course, is you can't play across a break (which
you can't see) and mark in on the fly; you have to stop the deck after
every camera stop to make sure DS is seeing the correct code.

This could be an RS-422 protocol thing, or a DS thing, or a Panasonic
thing, or (in your case) a Miranda thing. 

Or sunspots.

Well had a worrying discovery this morning whilst testing the lasted
beta version of the Miranda HD bridge software.

Noticed that when I click play on the DS the servo light comes straight
on and the capture tool timecode starts counting from the timecode it
last had in stop.
The thing is the HDV transport takes approx 2 seconds to startup and the
timecode showing on the Miranda box doesn't start till a few seconds
after play is pressed. The result is that the DS timecode is now some 2
seconds ahead of the actual offtape timecode. When stop is pressed on
the DS the timecode on the DS snaps back the few seconds.
So it's possible the Miranda is falsely signalling that the servo is
locked and tricking the DS to thinking the timecode should be
progressing.
But it's frightening to image that the DS doesn't even both to check
that the timecode coming down the RS422 isn't in sync with what it's
counting.
