Non-standard genre

[ToddBethel]

I've been working with UltraID3Lib, and it mostly does what I was hoping for. I've run into one problem, though. The main reason I was looking for something like this was because I don't like the native ID3 support for genre information -- it's not flexible enough; I want to be able to work with non-standard genres. However, I just discovered that UltraID3Lib won't let me write ID3 data if the genre value I've selected is a non-standard value. Can you tell me what I need to be able to do in order to write non-standard genre values?
