Re: Missing EPG data

The code has changed in 0.10.23 but the rootcause remains i.e. unlock() spec is not fulfilled: 
"Unlock any pending access to the resource. Subclasses should unblock any blocked function ASAP. In particular, any create() function in progress should be unblocked and should return GST_FLOW_WRONG_STATE. Any future create() function call should also return GST_FLOW_WRONG_STATE until the unlock_stop() function has been called."

gst_dvbsrc_unlock() calls gst_poll_set_flushing() with flushing set to TRUE
http://cgit.freedesktop.org/gstreamer/gst-plugins-bad/tree/sys/dvb/gstdvbsrc.c?id=RELEASE-0.10.23#n1090

gst_poll_wait() returns -1, with errno set to EBUSY
http://cgit.freedesktop.org/gstreamer/gst-plugins-bad/tree/sys/dvb/gstdvbsrc.c?id=RELEASE-0.10.23#n921

gst_dvbsrc_read_device() returns NULL
http://cgit.freedesktop.org/gstreamer/gst-plugins-bad/tree/sys/dvb/gstdvbsrc.c?id=RELEASE-0.10.23#n953

gst_dvbsrc_create() returns GST_FLOW_ERROR instead of GST_FLOW_WRONG_STATE

That (its second part) doesn't properly apply to the debian source
(which is 0.10.23).
