I've tried Yadif after Decomb Telecide and it does produce nice results. There were still a few
very minor comb artifacts on certain rounded edges, so I tried running "field bob" in VDub in conjunction with the AviSynth script of Decomb Telecide and Yadif. That seemed to take care of all the jagged edges and I don't think the quality suffered. Of course now I'm noticing all the other weird problems with the video - like the frequent wobble across the middle of the screen.
One thing at a time for now...
