[linux-dvb] Write_dst error during scan on Twinhan DVB-T mini ter

If I run a scan as follows:
 ./scan dvb-t/uk-CrystalPalace

I get a list of _write_dst errors in dmesg and get "tuning failed" 
during the scan.

The results of the scan are as follows:
scanning dvb-t/uk-CrystalPalace
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
initial transponder 505833333 0 3 0 1 0 0 0
 >>> tune to: 
WARNING: >>> tuning failed!!!
 >>> tune to: 
(tuning failed)
WARNING: >>> tuning failed!!!
ERROR: initial tuning failed
dumping lists (0 services)

The errors in dmesg (occurring during a scan) look like:
write_dst: _write_dst error (err == -5, len == 0x08, b0 == 0x07)
...<repeated lots of times>...

Any ideas what this means?
