Python web scraper seems slow

I've just created my first python web scraper for use with Kodi and it seems to be slow. It is for a local TV vod website here in New Zealand. It fetches the show lists pretty quickly but when fetching the episodes it seems very slowly especially when compared to the shows fetching. Any help on how to improve my code so it runs quicker will be much appreciated.

Hope someone can help me. I'm relatively new to python so I possibly haven't gone about things in the best way. Thanks all
