I am not certain how to make sure at least 2 bytes are left for data blocks in the CTA-861 extension block. Is this a setting or some number I am setting somewhere in CRU? I am guessing this will either help in general setup or get my 8K AVR to recognize the CRU setup?

CRU tells you how many bytes are left in the data block list in the extension block. NVIDIA's driver has a bug that causes it to ignore all changes if there aren't at least 2 bytes left.
