Anyone has any link for different Quantize Matrix than the default one already available with TMPGEnc?

I did read somewhere that changing it from default to mpg standard will de-crese macro-blocks?
Not sure but you might want to give it a try
Heres something I found that may help ya:
THE TMPGENC MACRO BRICK NOISE SETTING(aka soften block noise setting)
This setting on the TMPG(and it is found under the "quantize matrix" tab of tmpg) will and can reduce the "block noise" commonly associated with video cds(mainly at normal rate, but not all the time).
Again i have found with a lot of testing that if you have this feature on, i keep the intra and non intra blocks the same number. Older versions of TMPG kept the setting at 35 for both. This is a good rate to use, actually 35-40 was ok. Going higher (at least from what i found) resulted in extra block noise that i did not want.
ALSO while under the "quantize matrix" tab, click on the "floating point dct" box, this will help produce a better picture for you.
FOR HIGRATES/XVCDS/SVCDS - i never really use the soften macro noise filter, as the bitrate is high enough to compensate for any brick noise that would have been made using the normal rate vcd setting.
ALSO i did not use this filter for anything with the quality of a dvd rip.
