I didn't express myself quite right there. I have an upscaled but possibly warpsharped source. The original was mastered in either HD or SD, i cannot tell as the anime uses very clear lines and simple backgrounds. I believe this source was SD originally before upscaling, however either the station or capper thinned the lines somehow. So i have to downscale this source, however by downscaling it, then msharpening (maybe i did some AA too, i can't exactly remember, i should go look up my scripts), i end up with it looking more blurry/worse than the original upscale.

And for the "when/how do we know", I can really only offer the "use your eyes and use what you like better" advice. A rule of thumb seems impossible for me to formulate, since you never really know what happened to a source you're in front of in the past. Then again, it really doesn't matter at all, does it? Pick the version you like best.

I'm afraid I offered very little useful advice, but - that's the best I can come up with right now.
Most people seem to recommend Spline36 or Bilinear for downscaling compared to lancos3/4, and i'm under the impression that lanczos3/4 makes for more blurry images when downscaled, while bilinear makes edges more jaggy.

Actually, your previous post clarified quite a few issues for me, thanks.
