Strange about changing mythbuild.sh, my copy of mythbuild.sh contains 
below the deb lines which should have forced the correct architecture 
(this was one of the changes Lawrence made)

   APT::Architecture "armhf";
         APT::Architectures "armhf";
         Dir::Cache "$cache";
         Dir::Etc "$AptRoot";
         Dir::State::Lists "$lists";
         Dir::State::status "$status";


As far as I know the disabling of hdhomerun  only affects mythtv-backend 
which is not on RPI2, not the frontend, but I could be wrong as I don't 
have any hdhomerun units.
