In the limiting case of running a low-latency stream
and hitting a long dropout (many hundreds of
milliseconds), the video artifact (a still image) is
much less objectionable that the audio artifact
(a concealment algorithm hitting its limits of
pleasantness, or a dropout).   So, I'd say audio,
since its the limiting cases that tend to make
customers say "this is junk".
