Replace the original XVid4 render profile:
acodec=libmp3lame ab=%audiobitrate+'k' ar=44100 vcodec=libxvid minrate=0 vb=%bitrate+'k' aspect=%dar mbd=2 trellis=1 mv4=1 pass=%passes

With:
f=avi hq=1 acodec=aac ab=%audiobitrate+'k' ar=48000 pix_fmt=yuv420p vcodec=libxvid minrate=0 vb=%bitrate+'k' g=250 bf=3 b_strategy=1 subcmp=2 cmp=2 coder=1 flags=+loop flags2=dct8x8 qmax=51 subq=7 qmin=10 qcomp=0.6 qdiff=4 trellis=1 aspect=%dar pass=%passes
