 Here's me with my Sony eye candy video again, encoding to 3GP (MPEG-4 simple + AMR), keeping the aspect ratio by padding it with black bars:
 <code>
-avconv -i Sony_Bravia_-_Eye_Candy_HD_1080p-jfdMo4b0U_Y.mp4 -ac 1 -ar 8000 -vf scale=176:100,pad=176:144:0:22 -vcodec h263 -ab 12.20k -r 15 video.3gp
+ffmpeg -i Sony_Bravia_-_Eye_Candy_HD_1080p-jfdMo4b0U_Y.mp4 -ac 1 -ar 8000 -vf scale=176:100,pad=176:144:0:22 -vcodec h263 -ab 12.20k -r 15 samsung.3gp
 </code>
 It does support MP3 and AAC playback! You can also do playback with H.264 video on baseline profile. Pretty awesome for a little guy. :)
+<code>
+ffmpeg -i source.mp4 -r 15 -vf scale=176:144 -vcodec libx264 -profile:v baseline samsung.mp4
+</code>
+And here's ripping a DVD from Handbrake:
+<code>
+HandBrakeCLI --format av_mp4 --encoder x264 --encoder-profile baseline --encoder-preset medium --rate 15 --aencoder fdk_aac --mixdown stereo --width 176 --subtitle none -i /dev/dvd -o samsung.mp4
+</code>
