Glenn, Thinking about you're problem a little further, I came up with a few
more thoughts. The fact that you're seeing the external TC switch back to
internal TC in preferences indicates to me (at least from the way the software
works in my setup), that for whatever reason, the Sunrize board isn't
recognizing the external TC as valid time code, and (as mine does under the
same conditions) is therefore switching automatically to internal time code
which is essentially free wheeling compared to any external time code.
Then in your comments, you mention that you're recording you're time
code on the PCM track of a Hi-8 tape. I've never tried doing that, and although
the specs would indicate that Hi-8 PCM tracks should be able to faithfully
playback recorded time code, the problem might be that the Sunrize board
doesn't like its time code PCM'ed. Or it might be as simple as an incorrect
(too hot, too little) level setting into the Sunrize board. I would suggest
some experimentation with the levels first. Then maybe try using the linear
tracks for the time code instead of the PCM. My guess is this might not be
practical real world as you can't post stripe using the linear tracks, but it
might give you an indication whether the Sunrize is choking on the PCM'ed time
code. If that's the problem, one solution would be to buy one of those time
code reconstructors (probably not the right word) that accepts somewhat corrupt
time code and outputs a reconstructed version of the time code. They're not
real expensive; I bought mine for about $200 bucks from a company called
"MIDIMAN". The box is called the SYNCMAN Plus. I seldom need it in my setup
anymore, but it's a versatile box well worth the money. It generates time code
for striping to tape which I use on shoots for striping right to the linear
tracks of my Hi-8 cameras (I don't have PCM capability). It does this
regeneration of time code trick. And it generates Midi time code synchronized
to either the time code coming in to it or the time code it's generating.
In any case, my main point is that I would be kind of suspicious of the
PCM tracks on Hi-8 capability to record time code and then play it back for the
Sunrize board. And even if other things work all right off the recorded PCM TC,
the Sunrize might be more finicky. And there are ways around that problem as
well (Linear tracks, TC regenerators). Keep me updated. I hate to hear when
people have invested serious money into a setup and can't get it to fly right.
