I have a 400 disc sony dvd changer.

Those are pretty much the codes I would want to
intercept.  The goal here being that you use the myth
remote to control the dvd player much the same way as
you would the movies played from files.   All a part
of the wife-proofing effort of my system.

Yes, the blaster would be switching the input on a AV
receiver when switching to a DVD movie versus a file
movie.  When you're done watching the movie, you hit
the exit button on the remote (Or whatever) and the
ir-blaster stops the dvd player and switches the
receiver back to the myth input and exits from the
"special" program.  The whole goal of all of this is
to have as seamless an integration as possible.  By
the way, what IR blaster are you using?
