Breaking the 4 MB media file limit

Hi I’m trying to do a couple of things. The first has to do with the 4 MB media file limit. I wanted to embed an MP4 video file on a secured page. The problem is WordPress will not allow me to upload a file greater than 4 MB. The file I have is 13.7 MB. Is there a way around this or do I need to host it on another site like YouTube and embed it as an object?

The other part to my question is I want to secure the page. We are planning to charge people to see the videos, which is why we wanted to host them. Is there a better way to do this? I have experimented with a plugin that allows us to password protect a page and found that to work.

Any advice would be appreciated.
