It's not that since if I change from yle 1 to yle 2 it's instant with 
channel up but there's a pause if I do it by pressing 2. Exact same thing 
between yle2 and mtv3,  pause if I press the channel number, absolutely no 
pause if I press channel up. 

I have two dvb-t cards in the box and I've set up the ca so that it never 
has to retune when switching between frequencies.

So, I'm guessing then that pressing the number key always causes a retune 
but channel up/down only if it is necessary.
