Youpee! It works! :-) Thank you!

I patched mjpegtools-1.6.1.92-1.src.rpm with your modification, the
resulting src.rpm (that includes the patch) is here:

ftp://andrei.myip.org/media/mjpegtools/

Essentially, if you rebuild mjpegtools with your change, mplex -O works
without problems on RH9. Here are some examples:

# mplex -r 10000 -f 8 -O 900 tahoe1-017.m2v tahoe1-017.mpa -o
test900.vob
# tcprobe -i test900.vob
[tcprobe] MPEG program stream (PS)
[tcprobe] summary for test900.vob, (*) = not default, 0 = not detected
import frame size: -g 720x480 [720x576] (*)
     aspect ratio: 4:3 (*)
       frame rate: -f 23.976 [25.000] frc=1 (*)
                   PTS=1.0792, frame_time=41 ms, bitrate=8500 kbps
      audio track: -a 0 [0] -e 48000,16,2 [48000,16,2] -n 0x50 [0x2000]
