Line 21 scc file Out Of Sync by 1 hour

I have a project for which I have added a CC .scc file to the main track. However, when I test the DVD Build, the captions are displayed EXACTLY one hour off. The original video, exported from FCP, has a start time code of 1:00:00;00, as does the .scc file. However, DVDSP's track time code starts at 00.00.00;00. I have checked in the preferences for DVDSP and I can not seem to find a setting to change the track's timecode base.

The DVD was created using an mov reference file exported from FCP. I set Compressor to encode m2v and ac3 streams overnight to see if I get better result.

So, before I go in to check the encode and rebuild, I thought I would ask:
1. could the DVDSP time code base be the problem?
2. Will using m2v/ac3 files resolve the cc timing issue?
3. If 1 and 2 are not the reason for the timing issue, what would cause the cc to offset by exactly 1 hour?

Any help or suggestions would be greatly appreciated.

TIA.

Well, I finally figured out the solution:

In the track's Other tab, there is a track offset. I set that to 1:00:00;00, and the captions all lined up.

No where could I find this documented!!
