I gave my parents a roku 1. I unregistered it from my account, and had them register it on their account.
They liked it well enough to get a roku 3, and a roku 4.
They don't need the roku 1 anymore. They have offered me the roku 1 back, but they don't know the password they used when they registered it. They registered the roku 3 and roku 4 with a different account name.
If I cannot re-register the roku 1, I suppose it's not very useful. What can I do?
