mpeg2dec confusion

[DvdKhl]

I'm confused about the different mpeg 2 decoders.
So thats what i know:
mpeg2dec uses YUY2 (a DVD has YU12 and the divx codec handles YU12 so there is an useless conversion)

mpeg3dec3 uses YU12 (but with this one i have a problem at the top left and the bottom right: there is a short green line, don't know if it's the fault of the decoder because after the croping it's still there)

MPEG2Dec PP mod (just have read about this one)

can someone please explain me the dis and advantages of the decoder or is there a best?

I'm using Avisynth 2.5 if you want to know.

-the green line problem is in virutaldubmod, but not in your final video file, so not very important

-mpeg2dec pp is the old name of mpeg2dec3, it work in YUY2
mpeg2dec3 work in YV12 (with a "V" and not a "U" :D ), colors are more beautiful, and the coding process is faster (useless conversion is avoided)
other advantages: you can use a mpeg-4 postprocessing (deblocking & dering) on your mpeg2 source (useful with bad quality DVD), correct the luminance with "lumafilter", etc... many fonctions

there's also mpegdecodeur from nic which works in YV12 colorspace and can decode mpeg1 and 2
