DRM help...

I'm not sure of you are aware of the Xiaomi Mi box, but there are some on XDA trying to deal with losing DRM when downgrading beta builds.Anyway, I thought you might be interested to read about the progress they've made. Apparently, on the mi box DRM resides in the kernel (if I read that right, I'm a user not a Dev). Here's the thread. Hope you find it useful.
