I obviated the need to sample fast enough to catch the ~40KHz IR carrier by
using the "IR Receiver Module" available at Rat Shack and other places.
This module demodulates the mess and gives you a nice slow data stream to
play with - about 1KHz seems typical.  Another advantage is that it's usable
across the room and so forth because it includes the amp and filter which
you'd have to go to some length to re-create yourself - not bad for less
than $4.00(US).  Beware that it can aparently be overloaded by bright, close
IR sources (remotes) and that your pulse timing may not be precisely
reproducable under all circumstances due to its low-pass filter.
