[MEncoder-users] need help with .mpg format

[Tom Poe]

Here's .mpg file as is:
http://www.ibiblio.org/studioforrecording/media/banders.mpg

When I type the address into firefox browser, on my PIII FC5 system, it 
loads and plays fine.  However, I have reports that it doesn't open on a 
Mac system, or a Windows system.  Here's the encoding commands I used:
]$ mencoder mf://*.jpg -mf w=320:h=240:fps=1/7:type=jpg -ovc copy 
-audiofile Open_Studios_theme_banders.ogg -oac pcm -o test1.avi
followed by:
]$ mencoder test1.avi -o new5.mpg -ofps 25 -vf scale=320:240,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

Can anyone help me work out commands that would create a video that 
starts with images, and results in a video with sound track that works 
on most computers?  Any help appreciated.
Tom
