I have a question:

How does madVR deal with the refresh rate reported by the source filter or splitter and ffdshow's video decoder and then if deinterlacing is activated within ffdshow?

For example:

I play a VOB file hard-telecined/3:2 pulldown at 29.970 reported by the source filter (navigator) and ffdshow, but then I enable deinterlacing within ffdshow. Now pure deinterlacement would keep the same fps of 29.970 and I realize that but what happens if I use AviSynth internally within ffdshow and inverse telecine it using tfm().tdecimate()? How does madVR deal with that? Does ffdshow report 23.976 as the new fps? Does madVR still use the rate reported by the source filter?

I feel like the problem gets more complicated with the introduction of user-added refresh rates...but I like it nevertheless.
