Multiple netflix accounts on one xbox, on different gamertags

It would be same account different profile. Kinda like having multiple profiles on an xbox. Also, I understand it’s currently not possible because of the system but it would be an change that is possible. Similar to how Netflix has multiple screens for one account with multiple profiles.

Yes to both questions. You can activate a Family Plan across multiple consoles. I have my nephew on our Family Plan who is in a completely different household. With Netflix you can activate up to 5 different devices with one Netflix account.

This seems like a Netflix problem, are you using the same account as your brother? I don't think you can use the same account if it has been linked up to PS3 because there are different ways to display video's ie silverlight and/or flash. It may be defaulting
to flash as it knows you mostly view it on PS3 (Unlikey, But Maybe), Xbox uses silverlight. Whatever it is it seems likley to but on Netflix's server side! As far as playing games and using other apps that is a network or membership issue. I hope you get everything
up and running!

To use the Netflix app on your Xbox console, your Xbox LIVE gamertag must be associated with a Netflix account. If you want to disconnect your gamertag from its current Netflix account so that you can sign in under a different account, follow the instructions
at Netflix Support

You might want to disconnect all gamertags (This includes PS3 and other devices) from your Netflix account then link up that one for your Xbox again that you want to use and try it again.

Hi there,

if the problem is that you want to move the xbox live account to another email address (Microsoft Account) then that is possible via the steps here:

But like mentioned you can not merge multiple xbox live accounts into one.

A smarter support person just suggested this. I can't try it, because I'm not home:

Your Netflix account is associated with any Xbox Gamertag that has used the service. Use the following method to associate your Gamertag with a different Netflix account:

Launch the Netflix app.

Press the Y button to go to the Search screen.

Using the arrows on your controller, enter the following sequence from the Search screen:

Up, Up, Down, Down, Left, Right, Left, Right, Up, Up, Up, Up

Once the Diagnostics screen appears, select Log in again.

You will now be given the option to sign in as a different Netflix member.

If you wish to disconnect your Netflix account from all gamertags associated with your membership, you can disconnect all devices from the Netflix website.
