Are you actually getting this warning? I don't see it in your log.

Whatever the case the block you pasted from _output_frontend_stats()
does needs some work. Those ioctl need to wrapped around LOOP_WHILE_EINTR
(as they can a do return EINTR from time to time) for example but
I'm pretty sure this is not the reason for your failure. Don't take
my word for granted though and try commenting out the calls to
gst_dvbsrc_output_frontend_stats () and see for yourself. You should
see no difference.
