They have released a software update for Premiere Pro. You will also find downloadable encoder presets on the update page.
The “MPEG Pro” plug-in is popular for editing MPEG clips in the Premiere Pro timeline. It reportedly also supports capturing from the non-standard Sony MicroMV format devices. There are known issues with the Panasonic DX-100, but a patch is available from MainConcept. Mark Bailey reports that this plug-in also supports HDV capture and editing. Note that this plug-in does not currently support exporting sequence markers as chapter points!
MainConcept also developed a standalone MPEG encoder and DV and MJPEG codec solutions.
If you use MainConcept products, you will find plenty of company in their Support Area Forum.
Mark Bailey often posts directly in the Premiere Pro User to User Forums.
