But if I have only four multiplexes available why should I need to get more 
than four tuners? Those four tuners already give 100% coverage. With 
sufficient virtual tuners it's possible to watch live tv without affecting any 

Although NEXTCARD does work, there's no guarantee the card you'll switch to is 
on the correct multiplex for the station you're trying watch. Depending on the 
number of tuners configured, you may have to try several times to reach the 
correct card. Although a minor inconvenience, trying to explain this to an 
elderly relative may not be so easy.

Another factor is signal strength. You can only split the incoming signal so 
many times before problems occur & depending on your location it may not be 
possible to split the signal enough times. Signal boosters will only get you 
so far.
