I have solved the problem - though I don't think it was related directly to Vista.
After installing the At-Large Recorder, I was asked if I wanted to use ffdshow Always, Now, Not This Time, or Never. I originally answered "always".
To get the At-Large Recorder to work, two steps were involved:
- I reinstalled the "ffdshow" codec. This was the graphic option I mentioned in my first note. When I reinstalled, I chose the option to "reset" all extensions associated with this codec. When I originally wrote, I could not remember this program's name. After discovering the name, I had to do some detective work to discover what it did and how to replace it. I finally figured it out.
- After restarting the At-Large Recorder, I found that my "advanced" recording settings had been reset - I reset these to "default". As I started to view the new recording, I chose to "never" use the "ffdshow" codec for the At-Large recorder.
These two changes seemed to correct the problem. Since I don't make changes to the "Advanced" settings and this was an original install, I suspect that these two problems are connected - though I am not sure how. Sorry for taking up your time.
