A common misconception is that by selecting a specific model of a device in the URC database, you're going to get a codeset that's completely customized to that model, with only the correct available functions and so forth. This isn't what happens - the model number just references the "best match" codeset, which is exactly the same as if you had found that codeset manually in the first place, or selected a "close match".

If you want something completely customized to your device... then the best method is to learn the codes! You'd think code learning was akin to walking on hot coals the way some folks try to avoid it...
