comment “crosshair” in MS excel
This works slow as hell (really - it takes 8 seconds and huge CPU load to switch the highligted cell, this is ridiculous and hardly tolerable) and erases the colours customized previously.

comment How to make an MPEG2 video file with the highest quality possible using FFMPEG?
By the way I have also managed to get it playing h.264 - just a bit of patirnce was needed, it was slower to load. I have an identical picture in WMV (PC only), h.264 and MPEG2 now.

I can consider the problem solved although playback is visibly slow at the most dynamic moments when using the TV and somewhat better when using an HDMI-attached DVD&USB player (and perfect on the PC). I am going to try decreasing the resolution to gain speed. Thank you for a great detailed answer.

-target pal-dvd solves the problem, -bufsize dosn't work (I have tried -b:v 7M -bufsize 7M -maxrate 7M).

I have copy=pasted a wrong part, @slhck, I am using ffmpeg -i "in.wmv" -f lavfi -i aevalsrc=0 -shortest -c:v mpeg2video -qscale:v 2 -c:a libmp3lame "out.mpg" of course.

I have tried the first command line you suggest (ffmpeg -i "in.wmv" -f lavfi -i aevalsrc=0 -shortest -c:v libxvid -qscale:v 2 -c:a libmp3lame "out.mp4") - it encodes about 100 frames and then starts flooding the screen with errors like [mpeg @ 02f69ba0] buffer underflow i=0 bufi=235538 size=239761 and [mpeg @ 02f69ba0] packet too large, ignoring buffer limits to mux it.

"Messing with the number of B-frames, motion estimation method or GOP size may tweak the quality a little but won't result in big changes." - may I just make every frame a B-frame and use no motion estimation with MPEG2? The video has a lot of VERY dynamic parts.

@slhck The TV set is Philips 42PFL3606H/58, I am encoding to H.264 with ffmpeg -i "in.wmv" -sws_flags lanczos+accurate_rnd -c:v libx264 -crf 20 -preset slow -profile:v baseline -level 3.0 -pix_fmt yuv420p -tune fastdecode -x264-params keyint=240:min-keyint=20 "out.mp4" - the profile is the lowest I know and even more tweaks are used to make playing the resulting file an easier task.
