So, therefore, it's probably just an MPEG-2 file with a ".nuv" extension 
instead of ".mpg".

The fifos contain the *decoded* (i.e. raw/analog) streams so that a tool 
like nuvexport can re-encode them, which is inherently a lossy process.  
We currently have no reliable way to re-package the unmodified A/V 
content from a Myth .nuv container into another container, except for 
avidemux2.
