You could use:

mplayer -fixed-vo file1.avi -ss 0:00 -endpos 300 file2.avi -ss 0:00 -endpos 
300 file1.avi -ss 5:00 -endpos 300

...et cetera.

Or generate the command line with a script:

#! /bin/sh

file1=file1.avi
file2=file2.avi

j=` echo -n "mplayer -fixed-vo "
    for i in 0 5 10 15 20 25 30 35 40 45 50 55 ; do
        echo -n "$file1 -ss $i:00 -endpos 300 "
        echo -n "$file2 -ss $i:00 -endpos 300 "
    done
    echo `

echo $j

Or use eval $j at the end to execute the command instead of printing it to 
stdout.
