Yes, that is the way it works.  In most databases, most of the storage
is used in the recordedseek table.  I should also say that I am not
opposed to changes to recordedseek - it is one of the good things
about MythTV as it makes skipping about in recordings work
excellently, and improving that is a good thing.  I just want everyone
to be aware of the potential for problems with databases as large as
mine.  Imagine how long a schema update might take if all of my
recordedseek had to be converted to a new format.  And it would be
dramatically worse if all of my recordings needed to be rescanned to
do it - how long would it take to just read 65 Tbytes of data, let
alone do processing on it?
