I am running into some trouble saving a file as a DV-AVI.

I imported about 10 minutes of video from my video camera and saved as an
AVI.
I took one small clip (13 seconds) from about the middle, and Drag to the
timeline.
I did a save movie and saved to wmv format (best quality for playback on my
PC)
This took about 3 minutes and generated the desired output.

Then I went back to the same project and did a Save As to DV-AVI format.
The % complete meter jumped up to 99% and stayed there for about 15-20
minutes, then finally finished (CPU utilization also went to 100% and stayed
there -- this seems like a good thing, it means it is working). When I
played back the AVI file, it contained the clip I requested (audio and
video), PLUS all the clips which came after it in the original file WITHOUT
AUDIO.

I have successfully created two other DV-AVI projects without this problem.
But this was an expiriment to find out what is wrong with my current project.
I am having lots of trouble getting all my clips put together into a single
video, and did this as a test. I have had to stop WMM and reboot several
times over the past day or two, and it seems to me that a temp file or
working directory or something as been messed up. I have tried going back to
the beginning of the project (delete all avi, wmv, mswmm files and recapture
the video again from the source), but this does not help. Every AVI file I
create now has basically the same symptoms with the desired video at the
beginning, then more video tacked onto the end w/o the audio.

Any help would be greatly appreciated.

Is it possible to remove / re-install WMM? Would that help?

Also, why does the % complete jump to 99, then hang out there for such a
long time?

Thanks so much.
