When you can playback a full long movie without frame drops/repeats.

Yes, force video = auto = DXVA deinterlacing at the moment. Film mode uses madVR's own IVTC algorithm, which currently runs on the CPU, which means it isn't compatible to native DXVA decoding at the moment.

There are more variations than just natively interlaced and telecined. E.g. there's content which was telecined and then overlayed with natively interlaced content. Or there's field blended film content. This is a really complicated topic. What you could do is enable madVR's film mode and then check if playback quality is good. If it is, then you very likely have a telecined film source. If you see combing then you have one of the other variants, for which at the moment you should better use DXVA deinterlacing.
