A colleague of mine (MonsterCross who knows much more about this than me) has been experimenting with stretching the kernel based on the scaling ratio.
I'm waiting for him to say he's happy with it.
There's been enough response to say that the current default kernel is not the best option, and the default will be changed (probably to the Mitchell Netravali).
See http://www.cs.utexas.edu/~fussell/course...tchell.pdf for info on this.
I'll probably plumb in the sharpness control to the dotted line in Figure 13 of the linked paper which allows you to tweak the kernel to be sharper (but ringier/noisier) or blurrier.
I can also connect a few of the other kernels to a scaling kernel control in the video OSD.
