WMP plays mpeg2 .tivo but only audio for h.264 .tivo videos (why?)

Running Win10. I recently re-installed Desktop 2.8.3 and that got the mpeg2 .tivo files playing correctly in WMP, but h.264 .tivo files play only the audio.

Note: My cable co doesn't broadcast any h.264 channels so the only way I have to create a h.264 .tivo file is saving a .mpeg2 .tivo with VRD TvSuite 5 using the h.264 .tivo Output Profile. Personally I have no interest in h.264 .tivo files at all, other than for testing my program VAP, link in signature.
