BT Infinity and Netflix on Roku 2 (Error message ui-800-3)

If you're having issues getting your Roku working with Netflix on BT Infinity, it might be worth trying to turn off parental controls.

It appears that BT enforce the use of their own DNS servers which causes issues for the Roku when connecting to Netflix (but strangely things work OK via the app on YouView).

This gave me the error message "Netflix has encountered an error. Retrying in xx seconds. Code: ui-800-3 (%MSL_INTERNAL_CODE%)

When trying to test the connection I got failures acccessing "nw-2-5".

Turning off (and then deleting the settings) parental controls within the "My BT" website fixed things on my Roku 2 (4205E) but I had to wait for a couple of hours after the changes.

Hope this helps somebody!
