Ailsa, I put this list on the board in 2007, and for the sake of new members not living in the IoM I'll post it again. You will see that some are for church records, and others are for civil registration (up to about 1900/01 for full certs, and to 1964 for indexes). Compulsory Civil Registration started in 1878 for births and deaths, and in 1884 for marriages, although there were some officially registered before those dates.
You will note that some of these films are of the indexes which you need to use to order the certs., but you should already have enough information from ManxBMD to find them on the film, if available.
I transcribed the details of a number of death certificates to add to an index on the BREW One-Name website, which might be of interest as it shows what details are given at which dates.
