I wanted to live stream content that requires DRM (an official movie). Does anyone have experience on best services to leverage together to make this happen?
Microsoft DRM + Windows Media Server is well proven. There are a few resellers of Microsoft DRM, by which you can get it done affordably.

there is also a free trial to test.
