Something like Plex Media Server to serve up your locally ripped movies is really only dependent on the power of the computer running the server and how many streams you want to watch at the same time. Same with something like MythTV for the PVR, although live TV watching/recording is also limited by the number of tuners you have. I'd guess something like Simple.TV is similar to MythTV, but limited to only 2 tuners and 5 connections at once.
For the Fire TV/Roku at each TV, I suppose you could try moving them around to wherever you need them, but the better solution is to just a Roku/Fire TVs for each. The little Roku Streaming stick is only about $50, but it's wifi only and a bit slower than a $99 Roku 3.
If you own and watch 8 different TVs, you can probably afford 8 Roku or Fire TV boxes.
