Agreed, though Myth has changed my personal definition of "watch TV".

Since very little of my TV "watching" is live anymore, I might argue that a 
single tuner is sufficient to "watch TV" and record a program simultaneously.

Since the OP almost certainly meant "watch live TV", then your answer is 

My first Myth system had 4 capture devices, 2 connected to cable and 2 to 
satellite receivers. I have since decided that was overkill, since almost all 
the programming on cable can be found on satellite.

About the only live TV I watch anymore is an hour or so of news in the 
morning, though lately I think that a news show recorded the previous day, or 
even the previous week or month, would be pretty much the same as the live
