Where is the best way to look for codes other than in the database. I have fairly unusual equipment Theta Casablanca and DaVid, Krell 250Mc power amps, Revox tape deck, Power Plant Premier power regenerator that do not appear to be in the code library.

In addition for the more common components such as Sony DVD recorder RDR-HX1000, Humax satellite receiver there appear to be a multitude of different code sets in the library and I am not sure how to select the correct one.

Thanks
