To MB1 and Wkag: bitrate and encoding matrices

[ninja.rogue]

Hi folks,
just for the sake of completeness, I have read almost all forum messages here and in doom9.org about matrices.
There is one thing that I have to ask Mb1 and Kwag, about using or not using MB1 matrix with very high bitrates.
Mb1 has explained that his matrix is suitable for DV interlaced source and high bitrate encoding.
Kwag has now got back to default matrix in his templates.
As I am encoding with PAL DVD settings with very high bitrates (about 9000 avg) onto DVD-R, is it coherent to use MB1 matrix or is this matrix only for low bitrate encoding?
Or, to be even simplier, is MB1 matrix suitable for which min bitrate?
My general encoding settings are ok, as I am using highest possible quality, CQ100 or 2pass-VBR with max bitrate = avg bitrate.
I personally presume that Kwag's template are suitable for lower bitrate than MB1 has underlied his matrix - given the CQ value used by Kwag.
Your reply is welcome!!
Have a nice day.
Paolo
