jacktradesy2k, there are so many de-noise filters for this particular task. Use any of them. As you are a GK user its even easy, select medium noise in "save & encode" window and do a preview. If it look there is again noise then user higher noise filter.(heavy noise).

If you want to use other( not found on save and encode window) avisynth filters, then there is a wonderful one called convolution3d. This filter is present in your GK\avisynth\ folder. Readme in docs folder.

And if you want only try resize filters then use bilinear resize. It throws off most of details, there by reducing the grain mentioned. Here too you can preview to instantly know the result.

Hope that is of some use ...

Don't be confused about Resize filters:) .
it is simple if you know what is the purpose of each.
Lancazos:Use this for maximum sharpness.
SharpBicubic:Less sharper
NeutralBicubic:More lesser details.
softbicubic:Again less.
Bileniear:Least sharper.
simple: Which sometimes cause blocky artifacts. Not recommended.

Hope that helps....
