NOTE: It has come to my attention that the aspect ratio flag on these files is incorrect, forcing everything to appear tall and skinny.
The simplest solution for a PC user is to download this free program:

Run it, and select the first .AVI, set the Display AR to 16:9, then save it as another file name.
Repeat this for the second .AVI.
Now all should be well. It's a very quick process, and will not affect the quality of the video.
Another solution, available in some programs like Media Player Classic, is to manually set the aspect ratio to 16:9.
I apologize for the inconvenience.
