There is no point in going on, and on, and on about something that is already common knowledge. Everyone assumes that online video will be a huge market. (Of course, we could be collectively wrong). Don't spend your valuable presentation time on this.
On the contrary, focus on your obvious weaknesses. Highlighting weaknesses does not mean shooting yourself in the foot by bringing up details that harm your investment case. Instead, think what questions any intelligent human being would have when listening to your story. There is no avoiding. If you don't address them, the questions will remain.
"So, you are trying to build a page rank-based search engine?" "Yes, exactly, you picked that up fast. Let me show you our cool technology and some pretty impressive first search results" Wrong answer.
