maybe..is the answer....
there are a few threads already on UKtvs and TDT and the issues that you may encounter with a freeview branded tv and tdt...including the thread just below this on entitled "TDT"
but it may help if...
the tvs country setting be changed to "spain"
the tv can scan digital frequency 69 - the uk does not use this frequency, spain does..
some uk freeview boxes do not allow you to change to the second / alternate audio soundtrack.
maybe post you tvs model number and maybe someone has that and is using it and can confirm....
