That is because your filenames don't match.
Your original file is:
NewGirl-S03E16-Sister-6186624-0.mpg
MCEBuddy is expecting the properties files to be named:
NewGirl-S03E16-Sister-6186624-0.properties
Where as your properties file is:
NewGirl-S03E16-Sister-6186624-0.mpg.properties
That is why it isn't able to find it. Is that something you can configure or is it fixed?
If it's fixed I can adjust MCEBuddy to look for the other filename
