If I were you, that wouldn't be a good idea unless you just want to post info on places like Youtube.
1. Do you have all the required permits to commercially sell DVD's to retail/rental stores?
2. Movie's/Documentaries take very high quality equipment.
3. Is it you that's giving information or your instructor (dad?)?
4. You haven't caught a salmon or steelhead yet, you need to know how to catch them consistantly.
5. Do you understand all the conditions (moon phase, temperatures, air pressure, etc.)?
Not to put you down, but legally/efficiently completing these kind of large projects are very hard. Think about it again, and think of what you don't have access to.
