Hi. Im quite new to mencoder and im wondering if anyone had some good tips on some good parameter values for this :

Mpeg2 PAL VBR (DVD spec) Elementary stream ---> Mpeg2 PAL CBR at a lower bitrate eg 4,5Mbit/s.

*Any suggestion on good and DVB compliant matrixes
*Any other "must have" parameters for max quality for mpeg2 encodes
*Howto do n+1 pass on CBR if its really needed
*Howto support Multiple threads during the decode/reencode fase, i cant seem to find the optimal options for this, any tips greatly apriciated.

The target viewing device is my little mpeg2 STB.

Would apriciate any anwser ;) (specially Sagitare ;))
