Another "interesting" thing with the TVE mux: I'm not sure I'm correctly
managing the performance counters of my usb stick, but basically there
are 2 post viterbi counters: an "abort count" (i.e. uncorrectable
packets) and an "error count " (number of error bits). By touching the
screen on the coaxial cable I managed to keep both counters at 0, still
the image is full of artifacts.
I remember seeing the same on some satellite channels: no uncorrectable
errors but still there are many artifacts.
Maybe they're using some non standard mpeg encoding (that both xine and
mplayer are unable to handle)?
