Hope this helps with what your asking. What you’ve read is true, Adobe’s encoder is not up to scratch with other encoders out there. However constant bit rate or CBR is always best, it is only 1 pass but the value is constant giving you a closer representation of the original files. Author to DVD and it should go straight to M2V file which is accepted by encore with no need for transcoding. Audio is as usual. Hope that’s what your asking. With adobe encoding your image will lose it’s detail and quality.
