[mythtv] render2019: step-length oddities in video editing

I use the editor to establish cutpoints in almost all my recordings,
cutting at keyframes. In 2019render 33b109b1106e the static images
shown at keyframes are often blurred, but stepping forward and back by
keyframes is consistent.
Nominal 1-frame steps forward are OK, and advancing around 7 frames
usually gives a better image; but steps back are by keyframe intervals.
Nominal 0.5-second steps do the same, and nominal 1-second steps seem to
go to keyframes in both directions. The larger steps aren't exact, but
I've tried this with both h264 and mpeg2 recordings. I haven't done a
direct comparison with master, but the feel is different.
