Thanks for the information.
And for your further email link regarding NewTec receivers - interesting.

RollOff means how steep the bandwidth filter prevents from interference by close transponders.
20% is somewhat better (sharper) than 25% but you will probably not see any difference such
as increased power and less lost packets. Originally EUMETSAT was talking about 5% RollOff but
only (Non Standard HW, AFAIK 20% is best for DVB-S2) NewTec receivers can possibly do that.
