How to Fix Hulu Error Code DRMCDM78

Disney-owned streaming service, Hulu, is one of the biggest competitors of Netflix. Though it might not compare to Netflix when it comes to paid subscribers, which sits around 35.5 million as of the third quarter of 2020, it has its own share of loyal subscribers.
