Hi,
I'm not sure what your setup looks like, but i assume that this usa ip you have is a vailid public adress.
Forget the bridge networking, that just complicates stuff, and you won't be needing that to watch netflix.
First of all you need to get a basic server client setup working. It looks like you're on windows, there are plenty of tutorials available for a basic windows setup(have a look through the openvpn communitiy documentation/howto). (My personal advice would be to use a setup with TAP adapters and not TUN, the final networking setup is easier to understand, because your server will appear asif it's on the local network connected to the same switch as your desktop)
Then on your server there are multiple possibilitys to route the traffic. If you want all data to go out the USA ip, just set the server default gateway to the USA ip's default gateway.
If you only want traffic designated for usa networks to go out of the usa ip, you should get a list (eg here:
http://www.iblocklist.com/list.php?list=us) of usa ip's and add the to your routing table and point them to your usa default gateway.
Once connected you need to make sure all (or certain) local traffic is directed through the tunnel.
PS: if you change your default gateway incoretly, you might lose all connectivity to your server. Make sure you know what you are doing, and have a backup plan. That vps should have a graphical console on some admin/webpage of your vps provider that you can use as backup.
But first, get a basic setup working, using TUN or TAP with DHCP and then come back 😉
