HDV capture edit compression noise... ???

Hello. Posted this in the JVC forum as well, though it probably should have just been posted here. I'm running a JVC HD110 720p at 30fps and capturing and editing on a mac platform FCP (studio 1) capturing HDV, edit native via firewire. I just picked up a 23" Samsung LCD HDTV and using that as a preview monitor. I see a fair amount of compression noise in medium tones where there is little variation in tone or color. Is this just HDV, or possibly is it better to change my capture settings? Capturing HDV but letting it expand into a less compressed format before dropping it into the hard drive? For instance having the project DVCPROHD but capturing HDV or AIC? Not sure that is even possible on the fly capturing anyway. I don't recall seeing the compression artifacts as bad coming out the component inputs of the camera. So have people had better luck with a Kona or AJA type card capturing from component from and HDV source?

Going from that to SD DVD the noise becomes very apparant. I experimented with exporting the HDV out to DVC PRO-HD then into DVD Studio Pro as well as Quicktime files, and both were significantly better final results than just going out native HDV. I'm betting its best to get away from HDV in editing ASAP and edit in a less lossy format.

i'm using the Z1 and get incredible of amounts of noise in the same areas as well. I'm importing HDV and then editing in ProRes and even viewing on a Matrox system. Any advice would be great!
