It looks as though TV Server itself is responsible for resetting the service dependencies. Procmon found no attempts to set the key value during boot, but the value had already been reset to the installation values when it was read to start the service. Procmon shows that SetupTV resets the service dependencies each time it is started. The dependency values do not change when I start or stop the TVService from services.msc. Reviewing the screenshots I posted above, I see that I could have changed the database dependency during installation. It would be nice if there were a way to change it without requiring a fresh install.
