Er, wait, I thought commas separated each code in a multi-code sequence... From your syntax it looks like you're using them to separate different codes for a single button in various situations... I'm confused..

I tried this: 

AD520C=20df0c.U,FFFFFFFF.NS

AD520C.L=20df12.U,20df03.NL


Which is what I think you were suggesting... And my shift key doesn't shift.

Should I just wait until you debug the IR trans chain?
