IMHO, the best solution is to take the smaller number of recordings and
stick them in MythVideo (and re-record reruns if you want to keep them
in TV).

The other option is to try to use the old, legacy, unmaintained,
use-at-your-own-risk myth.rebuilddatabase.pl or myth_find_orphans.pl
scripts (where you'll likely need to type in all the titles, subtitles,
descriptions, ...

The best approach when you lost your master backend would have been to
actually convert your slave backend into master backend on the same
mythtv database that the master backend you lost used--meaning you
backup the DB from the master (or use the newest, just-before-the-crash
backup from your normal backup runs***), restore that backup to the
slave backend, then change the slave backend to become the master
backend (and then reverse the process once you got your old master
backend up and running).

When it comes to MythTV, there can be only one database.  It's like a
Highlander thing.
