I'm getting an error when trying to authenticate with my cable/service provider. What does this mean? I have this network within my subscription.

This can happen occasionally. Please visit the full MTGO frequently asked questions page for troubleshooting steps for your device. However, if you do not have the MotorTrend network within your current cable/satellite package, then you will not be able to access the content. Feel free to check out the episodes under 'Unlocked Episodes'.
