Yes, I think that can do the trick. I got it to work, but I hope this
workaround can be more plain and clearly, if it is possible to "copy"
the DVD Scale button in some way to the File Render window.
I felt I had not completely control over what happened. By the way, here
is the procedure I think did work for me:
1. Loaded the HDV
2. Started File > DVD Render, selected Format: PAL (25.00) 16x9, Scale:
Scaled, and OK
3. Batch (DVD) Render window opens
4. Started File > Render and closed the Batch Render window
5. Edited file path and file name, File Format: FFmpeg - avi (or dv),
Audio: Preset avi_pcm, Video: dv_pal.avi, and before OK!
6. Open Set Format, verify the Canvas size has changed to 720x576 and
DAR 16:9, Switch Interlace mode to: Bottom Field First, OK
7. Lastly OK on the Render Window (5) and rendering begin
Confusingly 2. and 3 partly may create DVD directories which can be deleted.
Tried both TFF and BFF
The bottom line is that this trick and workaround created DV 16x9 files
which all displayed correct due to [SAR 64;45 and DAR 16:9] 😎
