Yep. From that thread sounds like QTGMC need special adjustment for VIVTC.
Problem: the source is a clip with mixed progressive/interlaced frames.
There are purely progressive frames, purely interlaced frames and frames contain both p and i area, like this example.
Problem fix: The jaggies are not caused by QTGMC itself, they are caused by TDeint.
Simply using your QTGMC call alone, without TDeint, results in a jaggie-less video.
The problem is you are wrapping QTGMC in TDeint. I suspect it is caused by the fact that by default QTGMC does not leave the original fields unaltered. TDeint does, so the interpolated fields by QTGMC do not match the original ones that TDeint injects, resulting in jaggies.

I tested normal QTGMC (non VIVTC) with same source and it produce same jaggies effect. So seems both use same script source.
