@neco Spline 64? Is that a cubic spline? Where do you see that option?

As for splines, they are very nice. Lancoz, which is what I prefer, can produce noticeable ringing, which doesn't doesn't occur with splines. Kick the number of taps up to 10 (for lancoz) and you will be watching anime through the blood pouring from your eyes (serious ringing). It also uses 1024 coefficients as opposed to the 16 used by bicubic (not cubic spline, I'm not sure how many that uses). If you keep the number of taps to around 5 or 6 the CPU usage isn't too high and the ringing is not noticeable around anything that isn't the credits or hardsubs.

I've never gotten warpsharp to work. How are you suppose to use it? I haven't tried in a while, but I remember that it always made the picture look worse.

[edit] Another thing about lancoz and bicubic spline is that while lancoz seems to preserve details better then the spline, the spine produces nicer looking lines. Lines enlarged by a spline filter are no more blurry then Lancoz, but tend to be smoother.
