I get this error everytime I reboot the mibox. It's happened from the day I unpacked the device. Google brought me to a post on r/Piracy that hasn't been answered and there are no other specific results on google. For the same type of errors I see clearing app cache and data but I'm wondering if this is a mi box specific error.
Try one of those startup manager apps to make vudu not 'run' at boot. Such as sdmaid, or 'all in one toolbox'
I never have figured out why all these apps have something that launches at boot. (Notifications perhaps)
I got this too in the last week! I had to block the recommendations from VUDU. Same thing happened with Hulu so that had to be blocked too.
Update: Clearing data and cache for Vudu fixed it for me
It's not a mi box specific error as that never happened to me with Vudu. It had happened with another app but clearing fixed it.
If you haven't cleared cache and data, try that.
