I just calibrated a friend's Pioneer 5080 using an EODLT and HCFR. The setup is identical to what I used to calibrate my 4280, except that I used his cheapo DVD player (component input) that doesn't process blacker-than-black.
On the 5080, the gamma tracking is a big ski jump looking thing - starts around 2.3, and starts diving all the way through 100% stimulus, down to low 1.x.
On the 4280, using my DVD player (also component input), the gamma is very flat except for 10% stimulus, which is a tad high.
My question is, can the DVD player hose up luminance that badly? I'm wondering if I should schlep my DVD player over to his place and repeat the calibration?
Something noteworthy: while calibrating the 4280, the gamma also started out with a downward tracking slope (but not nearly as drastic). Somewhere during calibration (I have no idea what changed/happened), the contrast setting I used to measure ~34 ftL on a 100% white window suddenly was giving me 26-28 ftL. But a beneficial effect that came with this weird change was the gamma tracking suddenly snapped straight - no sweat, just up the contrast control a bit. This happened some time between iterations of me adjusting R-high and B-high, and it hasn't deviated from it's very flat gamma tracking since.
