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.
