i have been unable to get mencoder to reliably generate an H264 that 
will play in quicktime.  the problem appears to be in the lavf muxer.  i 
use mencoder to generate a raw h264 video file, ffmpeg to create the aac 
audio file, and then mux them together with mp4creator:

mencoder "$infile" -vf scale=640:-10 -ovc x264 -x264encopts bitrate=1750 
-ofps 29.97 -nosound -of rawvideo -o "$infile.264"

ffmpeg -y -i "$infile" -vn -f aac -ar 48000 -ab 128 -coder 0 -ac 2 
-acodec aac "$infile.aac"

rm -f "$infile.mp4"

mp4creator -c "$infile.aac" "$infile.mp4"
mp4creator -r 29.97 -c "$infile.264" "$infile.mp4"
