Hello,

I have compiled 2.6.28 with the included DVB modules and with that
version all my cards do tune !!!

I just forgot to add CAN_DO_2ND... flag to the modules so I can't test
DVB-S2 right now, and of course the current v4l-dvb's hg source just
segfault like you repported here.

Is there something we can do in order to fix this hudge regression in
the v4l-dvb's hg ?
