It apparently had to do with buffering...

Here's what I ended up doing:

( echo "Pass 1" && $PASS1 && echo "Pass 2" && $PASS2 && echo "Pass 3" && 
$PASS3 && echo "SUCCESS!") 2>&1 \
    | tee $MENCODERLOG \
    | tr '\r' '\n' \
    | awk 'BEGIN {b=99} /^Pos/ {i=match($0,'/[0-9]%/'); 
a=substr($0,i,1);if (a!=b) {b=a; print $0}};! /^Pos/ {print $0}; fflush()' \
    | zenity --text-info --title "Ripping $TTILE"

It only prints the status line at every new % and it prints every other 
message.  I need to eliminate blank lines; that's next.
