Freeview STBs will use 4:3 or letterboxing, either 14:9 or 16:9, as indicated
by the AFD setting embedded in the MPEG stream. xine-lib has no support for
this wrt picture shape, though it does report its presence and value; there's
a patch which improves this. I've observed problems with it, though, when the
setting is changed.
