Re audio vs video cable losses: The difference is that video output and
input circuits are impedance matched in the video band to the cable's
characteristic impedance, while the audio equipment's input and output
circuitry is not (not less than 600 ohms, output; 100K ohms or larger,
input).  Therefore the cable attentuation, while perhaps much greater in
overall amount at video compared to audio frequencies, may not shape the
waveforms coming across as much in the video band as it does in the
audio, and thus causes less perceived video than audio distortion.
Hence you can probably get away with cheaper coax cable in the video
rather than the audio spectrum.

Re "Godzilla", etc.: Several contributers to this group have given
plausible evidence for audio performance improvement of relatively high
fidelity systems with Monster Cable, etc.  This is probably due as much
to the better connectors that come with these higher priced cables as it
is to the cables themselves.
