Can UK DVB-T actually support HDTV from a bandwidth viewpoint?
I vaguely remember reading somewhere that the bandwidth needed would
almost require a mux per TV channel, which considering they are lowering
the rates to cram evermore channels onto each mux would seem to something
that isn't going to happen...

Would it also need new Freeview boxes and/or PCI cards?
