How to modify Rset for AD7123 to get correct video levels again

In Revision C the video level for white was 1000mV and black was 300mV.

With Revision D of AD7123 the video levels are lower than the standards demand:

Black is now 271mV and white is 975mV, this is not acceptable.

 

Which value for Rset (data sheet says currently 530 Ohms) has to be used to get the orignal values again?

 

I guess that the formula in the data sheet was forgotten to be changed to these new currents and values?
