Any of the HDV presets should be chosen to convert files from AVCHD to HDV format for further editing in Premiere.
Have you successfully imported into PPro and not had it crash?
Yes, I did. I used Elecard Converter Studio AVC HD Edition v.2.1 build 80429 (!!!) and Adobe Premiere Pro v.3.2. But before opening converted files in Premiere, I had to rename files extensions from *.ts to *.mpg (since Adobe Premiere doesn't understand *.ts extension).
