The key word in the original question is "force". That is the wrong mindset as basically you cannot force everyone to pay given the technical limitations of the Internet on protecting content. Yes, there are more advanced techniques to better secure content but they tend to cost additional time/money to implement and can always be defeated by the more determined and technically savvy pirates.
A better way to consider the question is to instead ask how do you entice potential customers to pay for videos voluntarily and reward customers who purchase your videos even though pirated content will always be out there.
Something else to consider. Preach to the choir, not to the pirates. You cannot convert most pirates to paying customers but you can drive customers and potential customers into their ranks with anti-piracy rants and threats. When you do this type of behavior, in essence, you are advertising the effectiveness of piracy. Instead, encourage purchases and thank purchasers.

Keep in mind that "force" was probably a bait word used by the troll who was the original poster. As far as encouraging customers to pay for what they take we'll probably have to continue with providing a decent product at a reasonable price.
