Avisynth 2.50 ALPHA shifts collor channel...

Every new version of avisynth 2.5 since 11.04.2002 shifts collor component 16 pixels to the left when the source is MPEG2 and you use "DirectShowSource" and the collor space(output from DS decoder) is YV12... You can easy confirm that if you have ffdshow installed - check to enable MPEG2 decoding in ffdshow configuration and create a simple avs: DirectShowSource("d:\TEMP\MPEG2.VOB",fps=200) This is not a ffdshow bug!

What directshow filter are you using to decode the MPEG2? Can you confirm this using other input sources? PS. You should really use DVD2AVI and MPEG2Dec3 for MPEG 2 - much faster and much more reliable.

No problem. I just need to be able to reproduce the result - that helps :) As for this problem it proved to be a general bug, I hope you could live with the dealy. (Believe me - the speed gain you'll get from the feature "causing" this bug will make you ahppy in the long run. But now it's fixed, so let's everybody celebrate :) :D :D (ok, I'll return tomorrow, when I'm sober and see if this makes sense ;)
