I completely disagree.  I use Live-TV storage groups religiously.  If
LiveTV is not in the same SG as my recordings, I can choose to backup
just the recordings I care about, I can chose to RAID just my
recordings, etc.

Additionally, I created whats essentially a "WAF" storage group...
containing shows that, if lost, might shorten my life expectancy.  The
folders in this SG are rsynced to a separate machine for live backup.
Additionally I have a cron that notifies me of any recordings that are
too small to be useful videos so that I can try and remedy the
situation before the wife notices.

Storage groups are a very handy tool...and being able to create more
of them to suit your needs is what makes them so great.
