I now have one tuner for each possible multiplex plus one additional for LiveTV (which acts as the emergency tuner for when one multiplex blocks two physical tuners).

This improves the situation but does not get rid of it entirely (I don't recall the exact figures but fixed maybe 75% for me, it will depend entirely on your recording patterns).
