I’ve attached a script called DVDA_chapter_from_Vegas_marker.js that will take care of your problem.
Run it after you’ve rendered and then decide to change marker locations.

Here’s a note from the script’s author who’s name I cannot remember or I would give him/her credit.

DVDA chapter from Vegas marker
So, you run this, and it will create an SFL file. Make sure this has the same name as your MPEG video file. So, if you have a “My_film.mpg” video file, you will create a “My_film.mpg.sfl” file. Then, in DVDA, open the project, or if the project hasn’t been started, drop the video into the project. If, for some reason, the markers don’t appear, click on the “Load Markers” icon above the timeline, after first double-clicking on the video file in the project area.
Note: I have found that, for some reason, markers sometimes don’t appear at the correct location on the timeline. I have not been able to determine why this happens, but I have a way to workaround the problem. Open the script in Notepad. Find this line, near the top of the script:
var NTSCFrameTime : double = 1471.47; // 30000.0/1001.0 = 29.97….
Change the 1471.47 number to one of these numbers:
1472.9415
1271.47
1601.61836

I answer your second question in this rather lengthy thread (apologies for the double posting in it but I had no idea I had done that and can’t change it).
