I tried it more ways than I can remember, always the same results.. Horrible.
I found the CF in the edge was better than most gave it credit for with LD..
I tried the entec, the key digital This RCA unit, iscan duo, the iscan ultra, the ludgemom (spelling error I know, but it was the older one with what was supposed to be a fantastic CF)
Far and away the Crystailo was the best all around.. no question. The CF in my Sony KDS-a3000 was very good as well (yea, I was shocked too) and then the edge was just a good.. The rest were horrible in my testing, dot crawl, noise... just a mess..
Try a CLD-97 with the edge, it was pretty good.
