Thanks for your reply.
I did set the rate, using fps=30000/1001 as a parameter to -mf. Looking at
your command line, I realized that I did not explicitly specifiy everything
that is required for an SVCD-compliant MPEG. My modified command:
/* added keyint=1 in -lavcopts and -ofps 30000/1001 */
C:\DVD>mencoder mf://menu.jpg -mf type=jpeg:fps=30000/1001 -ovc lavc
=4/3 -of mpeg -mpegopts format=xsvcd -ofps 30000/1001 -aspect 4/3 -o
This did not improve the situation either. Remember, though, that I burned a
SuperVideo CD that worked using this mpeg, and I can view it in other
players. I was just wondering if the MPEG was compliant, or whether the
players were just tolerant.
Anyway, I found this in the MPlayer Docs, in the Frequently Asked Questions

So it seems that MPlayer cannot play MPEG still images. If I increase the
number of frames by copying menu jpg to menu2.jpg, menu3.jpg (don't know if
there is an easier way), I can view it in Mlayer, but I suppose that it is
not an MPEG still mage anymore.
