For anyone still with Netflix issues on the MiBox, see if your tv has an 'HDCP compliant' HDMI port, using that instead of the other 3 hdmi ports on my TV has fixed my issue

Still no guarantee. Many tv vendors have a very sloppy way of implementing all forms of DRM on their devices.

Run drminfo on the mibox. Its results can be considered authoritative.

The 'HDCP compliant' HDMI port on my TV was labeled as "Best" HDMI while the others were just labeled HDMI, however it was HDMI #2
