Ok this is what I did - keep in mind I wanted to do this as fast as possible with as little headaches so I didn't exactly follow best practices but ... whatever at the end of the day it works for me.
My Guide to Using the Scraper
1) Download and install Ruby. I installed it to the C:\Ruby\ directory.
2) Download the tvdb_scraper.rb, http://www.samsaffron.com/tvdb_scraper.rb. I placed it in the C:\Ruby\ folder from step 1.
3) Before using tvdb_scraper make sure your TV-Series follow this pattern: "The Simpsons\Season 19\01.avi"
4) Open command prompt and navigate to the ruby directory. ( cd C:\Ruby )
5) Now run the scraper on the desired tv-show location. ( ruby tvdb_scraper.rb "D:\Media\TV\The Simpsons\Season 19" --refresh )
6) Check the metadata, if everything is correct you can run fixnames to rename the files automatically for you. ( ruby tvdb_scraper.rb "D:\Media\TV\The Simpsons\Season 19" --fixnames)
