Biostatistics - Negative and Positive Predictive Values

Although clinical tests are sometimes helpful in establishing the diagnosis, they don't always tell you the truth. Well, don't worry, ATP does ;)
In this video we will talk about negative and positive predictive values, and how you can employ this concept with pretest probabilities to get a meaningful answer of your clinical test's results.
Contents:
0:15 - Negative predictive value (NPV)
1:22 - Positive predictive value (PPV)
1:46 - Prevalence
3:23 - Example about NPV, PPV, & Prevalence

At 3:20, it says that increasing prevalence decreases NPV, but I manually calculated NPV from the numbers used in the following example and found that there also was an increased NPV with increased prevalence. Do you have any further clarification?
