When I connect Microsoft DTV-DVD Video decoder to my transform filter, it doesn't send media samples. It looks like it only sends samples when renderer is connected to it. Is there anything that my transform should satisfy in order to be connected to MS DTV-DVD video decoder (related to DXVA or something like that). This happens only with some MOV files. Here is connection between DTV-DVD and Renderer:
