If the frontend (not the driver!) is smart enough to correct wrong
parameters, why shouldn't it do so? IMHO what counts for most people
is that they can watch TV ;-)

OTOH tuning will take more time when the frontend has to find out
correct parameters itself, and it's not portable because not all
frontends are smart. So one should specifiy correct parameters
if possible.

But how does one find out what went wrong if the NIT contains
errors? IMHO the best way is to silently let the frontend
correct things, and if the apllication cares it can use FE_GET_FRONTEND
to find out what's going on.
