The COFDM transmission layer used by DVB-T (as well as DAB and several other transmissions) mitigates against multipath issues to some extent.
I'm line-of-sight to Sudburytransmitter (9km away in Colne Engaine) so suffer no blockage, yet after 16th Nov I too have no ArqB channels. It's unlikely to be the frequency change as free-space path loss difference between 738MHz and 810MHz is only just under 1dB.
