DEF:  Wow!  A lot of struggle here, trying to get something that seems 
to work.  Your suggestion did the trick.  I was able to compile a bunch 
of images, and ran:
$ mencoder mf://*.png -mf w=320:h=240:fps=1:type=png -ovc copy 
-audiofile Open_Studios_theme.ogg -oac copy -o test.avi
then
$ mencoder test.avi -o new5.mpg -ofps 25 -vf scale=352:288,harddup -of 
mpeg -mpegopts format=vcd -oac lavc -lavcopts acodec=mp2:abitrate=224 
-ovc lavc -lavcopts 
vcodec=mpeg1video:vrc_buf_size=327:keyint=15:vrc_maxrate=1152:vbitrate=1152:vmax_b_frames=0
then,
opened Cinelerra, brought up a terminal, ran:
$ midentify new5.mpg
ID_VIDEO_ID=0
ID_AUDIO_ID=0
ID_FILENAME=new5.mpg
ID_DEMUXER=mpegps
ID_VIDEO_FORMAT=0x10000001
ID_VIDEO_BITRATE=1152000
ID_VIDEO_WIDTH=352
ID_VIDEO_HEIGHT=288
ID_VIDEO_FPS=25.000
ID_VIDEO_ASPECT=0.0000
ID_AUDIO_CODEC=mp3
ID_AUDIO_FORMAT=80
ID_AUDIO_BITRATE=224000
ID_AUDIO_RATE=44100
ID_AUDIO_NCH=2
ID_LENGTH=83.64
ID_VIDEO_CODEC=mpegpes
and set format options in Cinelerra, and VOILA!  Ready to discover the 
wide, wide world of video editing.

What is so extraordinary for me, as a computer-challenged user, is the 
frame rate concept.  I created 91 .png images, in order to have the 
screens display for the length of the audio file.  When I created the 
test.avi file, that seemed to work, using 1fps.  When I ran the next 
command, to create new5.mpg file, it automagically set the fps setting 
to 25fps, but displayed each frame for 1 second.  Can you point me to 
info on how that works?
