The way I understand it, the "d2v=" parameter in TFM is there so that TFM doesn't just look at the video footage it's being given, it also looks at the D2V file itself and gets hints from it on how to match the fields properly.Qyot27 wrote:The 'd2v=' parameter in TFM is an override, it isn't required, and TFM naturally assumes that the file loaded by MPEG2Source is the one it's working with. As an aside, I wouldn't recommend using PP=0, though.
I would imagine that problems may be caused if AviSynth doesn't want to autodetect TIVTC, which might be why the d2v parameter needs to be there for TFM to work for you (I'm assuming TIVTC not autoloading is the reason you're using LoadPlugin - as that's the only reason it should be there).
The d2v parameter is essential, for instance, if you have DVD footage that exhibits illegal field order switching (Excel Saga, Love Hina); TFM will then create a fixed D2V file for you that solves the problem and tell you where it is so that you can now change TFM to call the fixed D2V file instead.
