[GRASSLIST:3297] how to interpolate a raster?

Hi,
I'd like to smooth or interpolate a raster but I don't know how to do it.
I tried with r.surf.idw but the result is not good for me.
Are there other metods more flexible?

Thank you
Leonardo

One alternative is to convert the raster to a sites file with
r.to.sites then use s.surf.rst.
