@Danne -- You asked me to do a test comparing the antialiasing feature in MLV App against a Mosaic Engineering VAF filter on my 700D. Here is my first attempt shooting one of our favorite subjects, our computer's keyboard. This is shot at 1736x976 with 3x3 sampling. That setting tends to show aliasing.
Processed through MLVFS and the DNGs converted to TIFFs using dcraw. I like doing it this way because it doesn't smooth out the problems like Adobe Camera Raw does.
Not much difference if you look at the whole shot on a computer screen.

If you look closely you can see a difference. Both of these were magnified 1600% in Photoshop.

I tried to pick frames that showed the D in focus. The VAF will soften the image slightly, though it is hardly noticeable if you look at the full frame. What does show up is that the edges of the shot without the VAF are some sawtooth looking edges and colored artifacts that are sometimes mistaken for focus pixels but they only appear on high contrast edges.
Now let's use these export settings so we can compare to the TIFF created in dcraw.
No VAF processed through MLV App with the above settings.
Once again the original for comparison:
Not exactly the best test--I should probably go outside and shoot a bicycle wheel. However, it does show marked improvement. Most import, I believe, is that the colored specks on the edges are gone.
