Thanks for the response. I fixed it by clearing the Prefer OpenGL
deinterlacers check box.
This gave me
mythvideoout.cpp:393 (SetDeinterlacing) VideoOutput: SetDeinterlacing
(Doublerate 1): Single High|CPU Double High|CPU
which works great.
I have no idea whether I have set that flag myself or if its the default
setting in the OpenGL High Quality profile, hence my query on how to get
one of these provided profiles back to its defaults.
Update - seemed OK but isnt, Audio sync can randomly go completely out
by several seconds.
Have to go back to VDPAU which unfortunately has panning issues on some
low bit rate HD channels.
