Garbage in, garbage out.. With DV footage you can only do so much. Applying filters to good footage will get you to 60% of simulating the film look, but even then it's very time consuming if you want to get beyond that point. Simply put there is no "one click" magic button to insta-filmlook
Also just because you shoot with film doesn't mean it will look better. I've seen plenty of crappy 16mm footage..
Getting a 3 CCD camera like the panasonic DVX100 or HVX200 will help with the colors. But what it really comes down to is actually free and available to you on any sunny day.. and that is good lighting. Shoot in the early morning or late afternoon when the sun is low and always make sure the sun is coming over your shoulder. That will get you started in the right direction.
This is a good example of good lighting and a DVX --> Gator Houseboat Video
