so now to my experiences:
the defaults (doc-file) read:
Cnr2("oxx",8,35,192,47,255,47,255,false) which is really okay for the 2.4

approximately (I have not tested exactly, simply used my eyes cause they are what I'm finally filtering for

) the same results using 2.6.1 are achieved by the following settings:
Cnr2(mode="oxx",scdthr=8,ln=16,lm=192,un=23,um=255,vn=23,vm=255)

So it seems the n-values have to be halved for some reason. But then it works as expected. I didn't compare the SCDTHR however, I trust you (@tritical) with this

@hartford: try to halve the n-values and compare the results to the 2.4 please ... (using PNG to save a screenshot helps: if filesizes are about the same, then the result in this special case is about the same, too - my experience! Or use avscompare, to be found at doom9)

addendum: I only tested YUY2 because I'm filtering captures, and YUY2 (besides UYVY) is the only color space my capturing card supports.
