Ahh, nothing like actually trying the command. The "a53cc" option has to be
used outside the internal parameters of x264.

ffmpeg -i INPUT.mpg -c:v libx264 -x264opts keyint=123:min-keyint=20 -a53cc
1 -an -f mpegts OUTPUT.ts

Here is a (working and tested) command line version, and the full command
output:

C:\>ffmpeg -i cea708_dtv.mpg -c:v libx264 -x264opts keyint=60:min-keyint=30
-a53cc 1 -an -f mpegts OUTPUT.TS
