MoCa and old ActionTec 424 wireless router

I am a newb here, don't know much about networking other than experimenting with gear.

Can I just plug in an old Actiontec Router 424wr into a MoCA to create a new wireless signal for a hard to connect area of my house?
Do I have to change it to an Access Point?

If I have to convert the Actiontec Router 424wr to an Access point, can I plug an ethernet cable into it and run it to a DVD that does internet televison (Like Netflix) ?
