This sounds good.

What I am missing is an identifier for the modulation (DVB-S2, DVB-S
and/or others), so you don't need to specify the modulation parameter
for szap (szap -t 2) every time you want to tune to an other channel.

Ok, good point.

What about like this then:

nPSK:DELSYS:IS:0xff

Where nPSK represents whatever n=B/Q/8/16A/32A PSK, DELSYS=DSS/S/S2 
indicates that it is a DSS/DVB-S/DVB-S2 system type. Thereby all system 
specifics 
will be followed by eg: S2:*, thereby better readability.

Why nPSK should come ahead delivery system:

* delivery system is a subset of the modulation
* not all 8PSK modulation is DVB-S2.

Comments ?

Manu
