I do not know whether the following issues are bugs, so I will save a
full bugreport with all the output for later.

I cannot play MPEG still images in with MPlayer. I tried -idle, -loop 0
and -fixed-vo. All I saw was a green MPlayer window flashing very fast.
Without these options, the MPlayer windows appears and disappears
immediately.

I created the MPEG still image from a 704x480 JPEG like this:

mencoder mf://menu.jpg -mf type=jpeg:fps=30000/1001 -ovc lavc -lavcopts v
codec=mpeg2video:vbitrate=2000:vrc_maxrate=2500:vrc_buf_size=917:aspect=4/3 
-of
mpeg -mpegopts format=xsvcd -o menu.mpg >> mplayer.txt 2>>&1

At the end, MEncoder reports:
Video stream: 9594.006 kbit/s  (1199250 B/s)  size: 40015 bytes  0.033 secs  
1 frames
However, mplayer -identify menu.mpg gives ID_LENGTH=0.00.

I can play menu.mpg in MS Media Player and Media Player Classic. I get
the same result with MPEG stills copied from Michael Tam's demo SVCD,
although I noticed that in MS MediaPlayer, my MPEG looked like a short
clip looping indefinitely. The picture did not move, of course, but the
progress slider kept jumping from left to right. The demo MPEG did not
cause the slider to move.

Nothwithstanding all the above, my SVCD's menu worked perfectly.

To summarize, my issues are:
1) I cannot play MPEG still images in MPlayer
2) There is a difference between my MPEG still images and others,
   although it does not seem to be critical

I am using MPlayer/MEncoder dev-CVS-060124-18:40-3.4.2.
