I have been looking at this guide Paths Reports .
I don't quite understand what the difference is between the two, if some could provide any examples that would be great.
Great question. The difference here is that an Original Entry page is the Entry page from a Visitors first visit. Each time you visit a site it will log the first page view as the entry page for that visit. This allows you to see which pages are pages drawing visitors to your site. Though you may like to know which pages drive the most first time visitors and the original entry page report will allow you to see that data.
Hope that helps answer your question!

Consider a New Visitor is arriving your website and the scenario stands the below:
Visit 1 : A >> B >> D >> E
Visit 2 : A >> C >> D >> E
Visit 3 : B >> C >> D >> E
Visit 4 : C >> A >> D >> E
Entry Pages are A, A, B, and C. It will be counted for every visit.
Original Entry Page is Only A. Till you clear your cookie, your Original Entry Page will remain A for the visitor because it is the First Page of your visit to the website.
Hope this explains the difference.
