Excellent approach to playing your monochrome DVDs, Penthode!
FYI... On professional broadcast color monitors in the 1960's and 70's, such as Conrac and many others, when color burst was absent the monitor not only killed color demodulation but also switched the Y video to wideband. If these monitors were properly converged, they were amazingly sharp for monochrome content without color burst.
I was so impressed when I first saw this that I modified my lowly home color TV to do the same thing! (Bypass the delay line and 3.58 filtering.) Even looking at an OTA signal at home, it was quite impressive to see the increased sharpness on monochrome content. Of course, this was in the days when burst was dropped on monochrome and before comb filtering became common.
RCA quadruplex video tape machines often seemed to have trouble dealing with loss of color burst. Many facilities that had RCA tape would complain bitterly if they got a tape to play or video to record that didn't have burst. Ampex machines seemed to handle this without issues. I always suspected that this issue and similar ones may have eventually contributed to the practice of burst never being turned off. However, at one time, it was not legal in the USA to broadcast monochrome with burst.
