Probably so.

Sounds like this could be used for what I'm talking about then.
We could use the "don't check for duplicates" flag in the
record table to set this flag in the oldrecorded table (so that
we don't use that row as a match for duplicate checking) if this 
isn't done already.

Thanks for explaining the above.  I haven't kept up to date with
all the oldrecorded changes, I still have to look in the code
sometimes when searching for things related to the different
flags and the scheduler. :)

You have a better handle on this than I do and from your
descriptions, it sounds like there are a lot of other ways to
accomplish what I was describing without having to hit the
recorded table, so I'm happy.  It will be a few years before
little Olivia can handle the remote anyway...  :)
