JAMU has modes for both local and storage group configurations, and
generally will do the right thing.  The only exception to this is when
people accidentally do a "half and half" configuration where they set
up the video SG but not the artwork SGs, leaving those as local
settings.  This isn't a supported configuration and JAMU can eat the
file paths, leaving people without imagery for their videos.

That said, in .24 and later, people should probably not run JAMU on
their video collection in any way (it is still useful for fetching
artwork for recorded programming, at least until I hook up the new
metadata classes to recordings).  When Jamu was originally written, it
was pretty analogous to the scan and fetch behaviors of MythVideo, but
there have been advancements in mythvideo scanning (levenstein
distance name matching, numerous new database fields, handling of
screenshots) that have not been added to JAMU.  The scan and metadata
grab in mythvideo/myth proper offers more accurate results (and in
cases where name matching is required, less interaction).  Granted,
for the metadata part needs to be done from a frontend still (though
I'm hoping to finally find time to get that fixed up by .25) but the
results are better and worth the tiny bit of effort IMO.  Mythvideo
also won't eat your metadata in the case of a misconfiguration, so
that's always good.
