MergeChroma(last, Trim(last,1))
or
MergeChroma(last, Loop(2,0,0))
But I suspect there's something more wrong. Post a short video sample of the original DVD MPEG2 video. -

its hard to notice while interlaced though (the original VOB is interlaced) the chroma error is only noticeable when deinterlaced

Looks fine in avisynth looked fine with VLC too.
I detelicined the video with this basic script.
Code:LoadPlugin("O:\Megui\Megui\tools\dgindex\DGDecode.dll") mpeg2source("C:\Users\.\.\dfg.demuxed.d2v") LoadPlugin("O:\Megui\Megui\tools\avisynth_plugin\TIVTC.dll") tfm(order=-1).tdecimate()

I'm pretty sure he loaded the MPG video into VirtualDub getting interlaced YV12, or passed interlaced YV12 into VirtualDub from AviSynth. VirtualDub doesn't handle interlaced YV12 correctly. There's nothing wrong with the chroma in the original MPG video. As you pointed out, a simple TFM().TDecimate() works fine. It needs some other cleanup too.

I converted them to AVI and wrote a simple script to load the AVI into virtualdub (it also converted them to rgb32)
also when i opened the original vobs in vlc they were interlaced (deinterlace is off)
edit: oh cool you fixed it -
