Do exist a good metod of upsampling chroma?

[zbozx]

I had read the forum almost one year, in special all around Pal Dv and the famous chroma jagginess. Wilbert said he will do a special version of reinterpolate420 for Dv. My question is if there are already any form of avoid this jaginess. I think the best form would be to output yv12 from ffdshow without upsampling , and then apply a special filter in avisynth. Implementing a good upsampling in Cedocida (Bicubic, Lanczos, edge...) woul be a good option too?

PAL DV's YV12 is different from MPEG2/4's YV12, which I presume to be the same as FFDShow's. Hence, there is resampling of chroma even when we use FFDShow's YV12 output.
