Render by Regions (CD Markers) does not create tracks cut on CD sector boundaries

You are correct. The CD Wizard way results in properly quantized markers.

I used to do it this way until PG1 suggested using the Move Marker’s method. I think that it used to work the same both methods. There’s a discussion about it here: Quantize to CD Frame Outside Montage, or Time Stretch within a Montage (but not "to cursor")? - #6 by mgoldey

Thanks for the quick reply!
