Bitstream means the DVD player will deliver exactly what auido track is playing on the DVD. PCM means that the DVD player will take whatever audio track it is playing and convert it to 2 channel PCM (exaclty like the format for music CDs).

The only reason you would ever select PCM is if you had one of the very first digital capable amps that only had a PCM decoder and no DD or DTS decoder. Obviously, these aren't around much any more.
