Does anyone have fragments of the video?

Not that I have seen, but you could do it for the community! :D

if you are going to install your own modules then you have to host odoo yourself, and if you do that then you don't have to pay odoo anything. You just don't get major upgrades as a free service. Odoo is free if you are willing to do the work yourself.

Sorry, what do you mean by install my own modules? Do you mean to develop my own module? Because I'm having a bit of trouble finding a good tutorial or guide on how to develop my own module on top of the OpenERP framework. Thanks

You said you want to develop your own modules/code. Odoo does not allow non-odoo source code to be installed on their saas servers. So if you want to do anything custom you need to host/install odoo yourself to have the control you wish. As stated before you don't get major version upgrade service (conversion of the database schema from one major version to another). And the second thing is the 1-click module install as stated by Ray Carnes above.
