From my brief looks at the files, it all looks OK, h264 video at 1280 x 5xx (528 or 544), 24 FPS, and MPEG-4 ACC or Dolby AC-3 audio.  I really can't see a difference between one that works, and one that doesn't.

VDPAU only works with certain resolutions.  If the resolution is not
supported by VDPAU, it falls back to software.  The supported
resolution limitations are in the driver notes.
