Hi, I found this old thread (http://forum.doom9.org/showthread.php?t=117041) and i it would be nice to know, is the m4g-hrm today a recommended matrix or a other (better?) one aviable? I'm looking for the "perfect" :D matrices for
DVB-S (SAT-TV, SD 720x576 anamorph)
DVB-S2 (SAT-TV, HD 720p or 1080i)
DVD
BluRay

Thank You ;)

I think the first paragraph in the first post of the thread you are referring to says everything you need to know ;)

Currently the cases that these cqms were meant to fix are handled very well by psychovisual optimizations within X264, such as Dark Shikari's aq, psy rd, and psy trellis, which usually work better then cqms, in my (and everyone elses) opinion. Cqms can still be usefull, but not most of the time, and certainly not for the majority of people.

Correct. No custom matrix is usually necessary. In fact, I've never found a case where it improved things. Let x264's psy optimizations do thinks for you :)
