Maybe try looking at the comskip.ini file that is being used. Sometimes the default won’t work and you need to choose another one. Here is a link to some ini files that may better suit your files.

Maybe the CBS Famewolf ini will work for this show as Dr. Quinn was originally on CBS. I have personally used the Comcast & Wilky13 files before with success.
This may help you to see the steps on changing the comskip file.
Hope this helps.
