Don't use "Match Settings" - decide who the viewer is and choose from a variety of presets to suit your needs. For instance look under "H.264" and you will find a YouTube Widescreen HD preset, or there are iPod and iPad presets, all kinds of options.

You are going from 25 fps to 29.97 fps.
And from progressive to lower field, that cannot be right.
As Jeff said dont use Match Sequence settings you end up with the wrong codec. If you want to make a quick preview that is ok but not for final output.
Use a preset or fill all the parameters manually.
