[mythtvnz] Deinterlacing problem on TV1 MotoGP broadcasts?

[David Moore]

Anyone here watch MotoGP on TV1 DVB-T? I believe they have made a hash 
of deinterlacing somehow. I can see a strong "comb" effect on motion 
across the frame. I believe deinterlacing is working fine on my system 
because I only see this problem in the MotoGP broadcasts. Also when I 
check Video>Advanced>Deinterlace during playback I can see "Temporal 2x 
(HW)" is selected which is what I would expect because that's what I 
have chosen as my primary deinterlacer. Anyone else seeing the same thing?
