ffmpeg delegates H.264 encoding to libx264, as does Handbrake. libx264 is an
excellent H.264 encoder -- I believe the BBC use it for encoding video for
iPlayer -- so anything else you may download is probably also just a fancy skin
To put it another way, ffmpeg is going to be just as slow as everything else
you've tried. There are various useful (or at least OCD) reasons for getting
down and dirty with the ffmpeg command line, but I'm not convinced that you
would get any useful benefit from doing this sort of thing the hard way.

Just keep the decrypted DVD images around and play those, which is good enough
and involves a lot less time and effort doing decent transcodes. It's not like
they take much space in this era of cheap 8TB disks, which are good for over
1,000 DVD images.
