[MEncoder-users] converting .mov to .mpg for DVD burning

[linuxhippy at verizon.net]

ok, I think I found the answer in the online documentation:

13.7.5.2. NTSC DVD

  mencoder -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd -vf scale=720:480,\
  harddup -srate 48000 -af lavcresample=48000 -lavcopts vcodec=mpeg2video:\
  vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=5000:keyint=18:acodec=ac3:\
  abitrate=192:aspect=16/9 -ofps 30000/1001 \
  -o movie.mpg movie.avi
  

If my input file is input.mov, where does it go in the above command and why is there an output for movie.mpg and movie.avi....do I need to burn 2 files to a US DVD?
