I recommend skipping Dynamic Link and exporting directly out of PP.
Use H.264 Blu-ray for BD and MPEG2-DVD for DVD, two exports, one for each. And then author two separate projects, one for each.
This will produce the best results with the least issues.
And also consider scaling to SD before encoding to MPEG-2.
Always, always use Maximum Depth & Render options when you need to scale - it takes longer, but looks much better.
Thank you Neil and Jim
There still some basic questions:
1- My camera = AVCHD 1080i
2 - In Premiere edition = AVCHD 1080i (already done for Bluray = very good quality!)
3 - Export from Premiere = ? (AVI? compressed/uncompressed / mpge/ others....?)
4 - Import Encore = ok, the same file above.
5 - Transcoding and Export Encore = mpg2 DVD
Also, where do I scale for SD?

When you export from a PPro AVCHD timeline to MPEG2-DVD you are changing the resolution to SD

Yes, but there is more to it than this.
When you render from AVCHD 1080i to MPEG-2 DVD, you are not only changing the resolution from a sort of HD (to my way of thinking, nothing that is interlaced should ever be described as "High Definition" as there is far more to it than the pixel count) you are also going down to an extremely lossy form of SD.
Personally, I would always split the 2 tasks & scale to SD first (interim 10-bit) and then encode that to MPEG-2. It seems to get better results.
I would first render from PPro as a 10-bit uncompressed quicktime (Aja codec or similar) or a lossless AVI such as Lagarith, and then run that to MPEG-2.
As the source & the final are both interlaced great care must also be taken to maintain the correct field order, or there may be a very nasty artefact issue.
I posted to export to MPEG2-DVD because that is what "most" people seem to do
What I actually do is export to Widescreen DV AVI and then use that file for authoring in Encore
The reason I export to AVI is because I do not care to get into bit budgeting and export settings, and by giving Encore an AVI file I am able to tell Encore to use automatic transcoding to make a "best fit" of video to DVD disc... be that single or dual layer
Again, this is MY way of doing this
I´ve got some better results by not using the Dynamic LInk and just exporting from Premiere in AVI (no compressed) and importing in Encore etc...Another better result came from export from Premiere in mpeg2 I-frames.
At this time I wonder why dynamic link (atlist for AVCHD 1080i) exist.
I still not happy with the results but my client will have a nice Bluray anyway.
Ann, for sure I will have to learn to use frame server - I have just downloaded Avisinth. Until that, I will not sell Bluray and DVD at the same time.
Thank you very much guys for the posts
hello, i just used Jim Simon's method of mpeg-dvd and preset (with some tweaks)
i just read to turn on max render / max depth for scaling down from hd to dvd
but i thought by turning on one of those messed up the gpu or something
or that it prevented 32bit effects to be processed (i hope i'm not confusing stuff)
anyway, i'm running a test: re export one segment of the baseball dvd with the same mpeg-dvd preset
and turn on max depth / max render
it will be cool if the project can look even better...

I believe the problem with converting AVCHD 1080i to DV NTSC standard is that both formats are interlaced. If you think about it, you're taking one high resolution interlaced video, shrinking it down then interlacing the it again. This dual interlacing combination creates a horrendously blurry video.
Understanding how the problem occurs leads to finding the solution and the solution I found is quite simple. Plus you can do this using dynamic link.
1. All you have to do is take your AVCHD 1080i sequence or footage and nest it inside of a progressive SD sequence.
2. Send that 480p sequence directly to Adobe Encore and let it transcode from that. The video will come out as clear as it can be. You can also try setting it to maximum render quality and maximum bit depth if you're really particular.
Settings I choose to get a 480p sequence: I just select the DV NTSC widescreen or standard presets then change the "Fields" setting to "No Fields / Progressive" for a custom sequence preset.
Note: Remember to scale the HD video to fit in the SD sequence.
Using this method, you can continue to do all your editing work in the main HD sequence and have the option to export for DVD when needed right in Adobe Premiere.
I'm not really sure exactly how this works cause in the end, we are still interlacing an interlaced video. I'm guessing that by creating the progressive sequence, we are forcing Adobe Premiere to render the video without showing interlacing frames so when Encore transcodes the frame, it is interlacing a faux full frame and not the true interlaced frame. Is there a better way to do this? Maybe. But this method is much less of a hassle for me. The results are great.
