I found that there are two MediaInfo programs. I downloaded MediaInfo as recommended by LS and MediaInfoXP as recommended by Sayln. Both seem to give the same info. The only difference I saw was MediaInfo lets me present the info in different ways such as text, HTML, etc.
Sayln, I agree with your comment about
: ""GSpot identifies the files as DV Type 2 AVI, 29.97fps, interlaced, bottom frame first, and in DVD format" doesn't make any sense." The DVD format indication came from GSpot. So I guess GSpot is more than just long in the tooth. It can present odd information.
Here is the text from the MediaInfoXP analysis of the whole video:

I used
VirtualDub to preview the video and got odd image movement when I stepped through the video. I got the following movement progression in both input and output panes as I progressed step by step with VD in Preview Progressive mode. Forgive the odd formatting. I had everything lined up, but my extra spacing was removed when I submitted the reply:
Step: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
Movement: y n n y y n y y y n y y y n y y
On my VHS capture I can view the field by field progression with the VD deinterlace filter set up with Yadif double frame rate and TFF enabled. The output pane correctly shows movement with each step while the input pane only shows movement every two steps.
Any idea what causes the odd frame/field progression I see as I step through the video frame by frame? Is it caused by the need to insert frames to adjust between the fps of the film versus the 29.970 fps video? I tried the VD deinterlace filter to check the input and output movement and got even stranger progression. This setup showed one movement followed by one to five non-movement steps. Plus sometimes only the input or output pane would show movement. I had never seen the input move without the output moving.
