Replying to myself, in case this can be of use to anyone.
I got this problem solved by using the following ffmpeg incantation:
ffmpeg -i 1.mkv -i 2.m2ts -filter_complex "\
" -map "[outv]" -map "[outa]" \
-c:v libx264 -crf 23 \
1.mkv is a video segment at 720x480, whereas 2.m2ts has a 1920x1080
resolution. The resulting video, A.mkv, is 1920x1080, without any
distortions, and it plays correctly under mplayer.
I do not really understand how the command above works; if I get some
understanding of it, I'll post explanations here in case, again, they might
be of use to somebody.
