The data base has some major issues as is evident from trying to use the 810 preprogrammed 'wizard' codes as well. The best thing is to learn in your codes (test them thoroughly), and then set up profiles/dummy devices/templates with the codes for the equipment you use most frequently, and use the preprogrammed IR database purely as a backup rather then a primary source when customers have random old gear and no working control (ie old beta vcr, or dat or something).
