This is the first i have ever developed for linux, cant really wrap my head around how to submit this.. Hope im sending this correctly, diff made with 'hg diff' from latest "hg clone http://linuxtv.org/hg/v4l-dvb"; It adds support for tuning with PSK8 modulation, pilot and rolloff with the S2 versions of firedtv.
