Vegas render looks good but not the DVDA video

[Posting this here as well as DVDA section, in case a Vegas issue- thanks!]

I just recently started using Vegas 9 Platinum and using Vegas put together video of football highlights shot in HD on a Canon HV30. I imported the video into Vegas in HD. I then created a 15 min video which includes some still images with audio and the video with the original audio. I want to burn it to an SD DVD.

Looked through the Vegas help and this and other forums to determine the best way to render and followed the guidance. I first rendered the video with MainConcept MPEG2 (Template: "DVD Architect NTSC Video Stream") and then the audio in Dolby Digital AC-3 AC3 Studio (*.ac3) - "Template: Stereo DVD". Both with same file names so the audio imported automatically into DVDA. When I then go into the Renders folder and play the newly rendered MPEG video file using Windows media, the quality is very good with very few artifacts.

I then add the newly created video render into the DVDA project window (both video and audio import with no problem) and I set up the simple menu structure with just a five chapters. When I use I use the DVDA Preview function the photos with voice-over play just fine, but the video is not very good, lots of artifacts and any horizontal lines/images in the video (for example bleachers, lines on ground, tops of buildings) show really major flickering; there is pixellation of the grass on the field as the camera pans, and the uniforms of moving players show some pixellation as well - generally looks very grainy. Audio works fine throughout. I then burn the DVD which has these poor results.

Frustratingly, when I first made a trial DVD some weeks ago, the video quality was a bit better, though it was my first attempt and I unfortunately did not write down the rendering settings I used ( do not think I rendered the video and audio separately at that time; but it played in DVD players and on PCs).

I think the steps I described above are the correct ones to follow and normally the result should be a DVD of better quality than if I had shot the video on SD to begin with...but this is not the case!

Any help much appreciated!

There is a response to your identical question in the DVDA forum.
It is not necessary to cross-post here.

After an extensive support session with Sony, please be aware that Vegas MSP9 does not allow DVD compatible MPEG-2 content to be rendered as upper field first.

If you have an HDV / AVCHD camera, it records interlaced video as upper field first.

When Vegas renders out your MPEG-2 files for DVD, it will be lower field first, regardless of your project settings. You will experience horrible shuddering and combing on fast moving sequences when played back on interlaced devices due to frame reversal. Note that the problem will not exhibit on progressive playback devices such as a PC monitor, but once viewed on an interlaced television, it will be painfully obvious.

There is no work around to enable upper field first rather than purchase Vegas full. Other industry players such as Apple have issued fixes for these types of problems, but Sony does not see it as a problem.

If you are thinking of editing interlaced HDV / AVCHD footage for DVD output, you'll need to find a different tool to achieve quality results.
