Timecode with capture and scene detection at DVinfo.net

(I originally posted this in the Adobe Premiere forum, but now I'm wondering if it's somehow specific to Cineform AVIs. Or something.)

I've been trying to find some definitive documentation about what happens to timecode on tape when one captures an entire tape.

Our camera (GY-HD100) is generating free-run timecode set to time-of-day.

When I capture an entire tape into Premiere, however, using scene detection, the individual clips do not seem to preserve the time code from tape. That is, while the TC looks fine on the camera/VTR display during playback, the batch list, when exported, looks something like:

Tape 15 00;00;00;01 00;00;02;26 tape_15 24.avi
Tape 15 00;00;00;01 00;00;50;11 tape_15 03.avi
Tape 15 00;00;00;01 00;01;13;28 tape_15 45.avi
Tape 15 00;00;00;01 00;03;22;17 tape_15 32.avi
...

(and in that apparently random order, too).

Testing by renaming the last clip from the tape (so it goes offline) and trying to recapture it results in Premiere rewinding the entire tape to the beginning, and beginning to capture from the beginning.

Am I missing something obvious? Is there no way to have a captured clip reflect the TC from the tape?

For what it's worth, this is a Cineform Aspect HD 720/24p project.
