“Does DVDA just not support importing chapter markers for a blu-ray?”
It seems that there’s still a bug around this issue.
Are you using DVDA 5.0b?
Here’s a workaround from the SONY DVDA forum.
I have a need for both DVD and Blu-Ray versions. So, I have rendered both .MPG and .AVC in Vegas. The MPG has perfect markers. So, I start of with the DVD version, complete it and save it as XYZ-DVD.DAR. I then re-save it as XYZ-Blu-Ray.DAR and start the process of changes: change properties, ADD AVC file to the timline (separate new video track). Save Markers. Remove old video track. Load Markers. Voilá. Done.
Instead of adding another track, would ‘replace’ video work? (after saving markers) I also frequently need BR & DVD copies of the same project. I find that DVDA throws up a few odd text changes when starting with DVD, then changing the properties to BR.
Yes, that works to, but (in my experience) if you first add as second video track and put the AVC up there as well. Simply remove that second track after you’ve done the replace on the first track. But… replace the video using the properties panel, track media.
