If you'd like to help getting this fix on dvbsrc, can you please
reproduce your failure with gst-launch and a recent checkout
from master and put your full command line alongside a
*dvb*:5 debug log for a failed run at bugzilla?.

For DVB-T2 you need to be properly setting: frequency, delsys,
bandwidth, code_rate_hp, code_rate_lp, modulation,
transmission_mode, guard_interval, hierarchy_information
and stream_id. Some of these parameters might have sane
defaults but please double check.

The "Failed to get statistics" messages should be harmless,
although It'd be good to know what the failing ioctl is. Right
now we are assuming the ones we use (_READ_STATUS,
_READ_BER, etc) always work.

Thank you,
