1st off, great job on such a great app.
My request is a couple basic filters which hopefully won’t strain the Wii too much.
GradFun/DeBand which removes blocking from what is supposed to be solid areas.
Sharpen – pretty self explanatory.
I myself would be very happy with those. I have some so-so quality divxs that could really benefit from those. I also have some good quality ones, so perhaps using a button like 2 to toggle filtering, with a settings section to toggle the filters.
