If you want to have a look at my own calibration chart: http://www.rone.go-plus.net/Calibrate/Black-White5mbit.zip Rather hasty, but I have black level, white clipping point and steps on one chart for my own need. Its a MP2 about 1/2MB and uncompressess to 5MB. Put it on loop as its only a 10sec file. Let me know what you think (it was rather a hasty attempt but I thought I'd share it with you.) No cocky comments about ripping off AVIA, this is my own chart created from my own material but does use a bit of AVIA inspiration. ROne.
