How did you check the FourCC?

That said, I just created a file with mpeg2video as such:
$ ffmpeg -f lavfi -i testsrc2 -c:v mpeg2video -t 5 ffmpeg.mpeg2video.avi
(albeit on Linux) an it plays just fine in (Windows) mplayer and VLC.

Could you please show us the full command line you used and the
complete, uncut console output?

Thanks,
Moritz

P.S.:
$ ffmpeg -f lavfi -i testsrc2 -c:v mpeg2video -t 5 ffmpeg.mpeg2video.avi
