This is an old thread. With CS6 dynamic link became rock solid for me.
My current work flow is …
1. Highlight clip on PrP timeline and Make AE Composition.
2. Work in AE creating desired effect.
3. Export AE project as an intermediary file (Prores / DNxHD / or whatever your prefer) MAKING SURE I HAVE PROJECT LINK CHECKED in Render Queue screen.
4. Import movie into PrP and use REPLACE CLIP to stick it on the timeline replacing the DL clip currently there.
5. If I need to revise in AE, I highlight the clip, right click and Select Edit Original to open AE, make changes and export again.
5. Rendering AE DL comps on the PrP timeline is very slow as opposed to exporting from AE.
There is no image quality loss if you choose a good intermediary codec to export your AE project to.
