Question:
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:
[Microsoft DTV-DVD Video Decoder]/(Video Output 1) -> [Video Renderer]/(VMR Input0) Major: MEDIATYPE_Video Subtype: MEDIASUBTYPE_NV12 bFixedSizeSamples: TRUE bTemporalCompression: FALSE lSampleSize: 3342336 cbFormat: 1152 Format: FORMAT_VIDEOINFO2 VIDEOINFOHEADER2: rcSource: (0,0,1920,1088) rcTarget: (0,0,1920,1088) dwBitRate: 752026352 dwBitErrorRate: 0 AvgTimePerFrame: 333667 dwInterlaceFlags: 129 dwCopyProtectFlags: 1 dwPictAspectRatioX: 1920 dwPictAspectRatioY: 1088 dwControlFlags: 679547009 BITMAPINFOHEADER: biSize: 40 biWidth: 2048 biHeight: -1088 biPlanes: 1 biBitCount: 12 biCompression: 0x3231564E biSizeImage: 3342336 biXPelsPerMeter: 0 biYPelsPerMeter: 0 biClrUsed: 0 biClrImportant: 0 and here is the connection between DTV-DVD and my transform filter:

Solution:1
it has something to do with the dwCopyProtectFlags=1! I think the video is copy protected. I have the same problem, but didn't find an answer jet. You can try it with an other decoder like ffdshow,
