I have not been following changes in avlib as of late, but at least
last year the way we parsed the language code for atsc was by passing
the pmt from avlib to lib/mythtv/avformatdecoder.cpp. So my first guess
would be that an avlib merge broke this passing of pmt code, which is
not present upstream. avlib parses some language stuff for DVB, but
at least in the past they never supported the language descriptors used
outside of Europe.
