I have a backend with 2 PVR 250s and a PVR500. I needed to have at least 1
tuner available all the time for Live TV and a second tuner for part of the
time for Live TV. With the number of tuners I have, this is workable. I'd
say generally you may want to keep 2 tuners for recording duties and add a
tuner for each tv that you would want to be able to simultaneously watch
live TV without interruptions (the backend asking you if you want to cancel
live TV so it can record) or to guarantee that you can watch live tv anytime
(mythtv not complaining of all tuners busy). Sometimes, I even have all 4
tuners capturing a scheduled show at the same time (hence no live TV), but
this is rare. On the average, only 2 tuners are busy recording shows.
One of my PVR 250's is connected to a motorola set top box. And as long as
that tuner is not busy recording a show, I can access it from any frontend
by changing to a channel that is only assigned to that tuner (example BBC
america). Mythtv handles the tuner switch transparently. Of course, only
one frontend at a time can access the set top box programming.
Hope this helps
