It could also be just interlacing.  I don't think the default settings
for TV Playback have a deinterlacer enabled.

Check Settings/TV Settings/Playback.  The first setting on the first
page is Deinterlace playback.  Turn this on and try Linear Blend or
Bob (2x framerate).

There are a great number of different opinions on what the best one
is, but just try a few until you find a picture you're happy with.

Having said all that, you can still get tearing, but I don't think
that's what you're seeing based on that screenshot....

Cheers,
