IRE Setting Workaround

From ISF Seminar - on the inside as reported by Michael TLV:

AVIA should not be used for grayscale calibrations. The IRE plates are not correct. This will be fixed in an upcoming version of AVIA. Use the VE to do grayscale, however, do not use the VE to do overscan geometry. Use AVIA here.

• This is not nearly as fatal ... but it throws the readings of a colour analyzer off by a couple hundred degrees.   Guy Kuo mentioned that some colour contamination got into the IRE frames. The human eye cannot see this, but the analyzer can.  The work around is to unplug the Cr and Cb outputs from the DVD player and use only the Y portion ... hence no colour information ... and the contamination is filtered out ... so to speak.  Guy Kuo suggests to turn down the colour sat to zero. One must realize though that on some sets, turning the sat to zero does not always mean zero.
