Glen,
The problem you're having (slipping audio tracks vs. SMPTE) I have
never seen. The other symptom (changing from external to internal) I have seen
and it may be related to your slipping problem. I have found that the Studio 16
software seems to "auto sense" where the SMPTE time code is. That is, if you
have it set to use internal time code but you have time code coming in the time
code input on the back, it switches to external time code. Likewise, if you
have it set to external time code, but none is coming in (or it thinks none is
coming in) it switches to internal time code. I have observed this more
switching from external to internal, but that is due to the way I tend to use
it in my setup.
Also, make sure that in preferences you have "Lock On" selected. This
is sort of a chase sync mode where it constantly adjust the timing of long
samples to match the incoming time code.
I have never seen this slipping problem and I use this all the time.
Somebody else suggested to make sure that you're time code was synched
correctly to the source you're trying to sync to (VCR?Multi Track Rec?) and I
would reiterate that suggestion. It may be that you're other source is the one
slipping. In my case, I record my time code on the eighth track of my
multi-track recorder and use the output of that track as my source there-after.
Because it's recorded on the tape, it has to be in sync with all the other
tracks on the tape, and the Sunrize always stays in sync with it.
By the way, how long are you talking about? I always work in time
frames from 1 Minute to about 6 Minutes as my main interests are music videos
with a few commercials on the side. I've never attempted any synchronizations
longer than about 6 minutes. Incidentally, my video is all digitized and played
back through a PAR/TBC IV combo synchronized through the SMPTE on the Sunrize.
Hope This Helps You,
Terry Tabor
