Today is the 7th of March and I have been seeing warnings about today's Freeview retune event. I have done a full retune on the LG HD TV and a "Smart" retune on the Humax FVP recorder. The latter preserves the recording schedule. Afterwards, neither TV nor recorder can see BBC News HD on 107 or the childrens' channels CBBC HD on 204 and CBeebies HD on 205. The FVP reports insufficient signal but the main HD channels (BBC1 etc) are all fine. Interestingly, the FVP knows what programme is supposed to be on and the Guide is fully populated. I just can't see anything on the missing channels. We are line of sight from the Sutton Coldfield transmitter, and signal strength is not normally an issue. I'm not really in touch with which multiplex is what, but I guess something is squiffy (technical term). Any suggestions on how to de-squiff? Thanks for any suggestions.
