 I'm seeing a problem when using VDPAU and Temporal 2X deinterlacing to
 watch NBC primetime shows such as The Office, My Name is Earl, etc. When
 watching these shows flashes occur at scene changes that look like
 previous frames are getting inserted. According to the playback logs it
 appears that these broadcasts have frames marked interlaced and
 progressive. If I force the video scan to interlaced the video plays back
 perfectly. Also when using BOB 2X deinterlacing I don't see any visual
 problems.


 You can download a sample below that visually shows the problem at a scene
 change and produces the mixed progressive/interlaced detection in the
 playback logs.
