re-imported tape, now clips are off

I re-imported a tape that had more video added to it. I deleted the original
import and named the new import the old tape's name. I was assuming that
since WMM will only import from the beginning of the tape that all the old
clips should sync to the new import. Apparently they do not. They are off
by two minutes for some reason. The project that has the old clips (when it
is opened) has the correct picture of the original clip for about 10 seconds
and then it is replaced with picture of the wrong clip.

Why are my clips' times off if it is the same tape from the beginning?
How is WMM seeing the correct clip preview for the fist few seconds of the
project opening?
Is there a way to edit the in/out times of the clips that are wrong (take
off 2 min)?

Thank you,

David
