I’ve a RealDebrid subscription and stream from their servers to my kodi. Not just Amazon, all the services. $3/month, give or take. Might take a few hours/days for something to pop up, but I often don’t realize days that shows are “airing” or released, so I’m pleasantly surprised when it pops up as available.
Buy the software. I tried the crack for a while at first too, but then I realized the problems I was encountering were directly related to the crack. (This is a number of releases ago) Back in the day they would ship you the DVR to install. Now I think steam is the only way.
