PCM is not Dolby Digital 5.1, but will handle Dolby Pro-Logic surround. So the short answer is, no, it will not do DD 5.1.

PCM (Pulse Code Modulation) is a common method of storing and transmitting uncompressed digital audio. Since it is a generic format, it can be read by most audio applications—similar to the way a plain text file can be read by any word-processing program. PCM is used by Audio CDs and digital audio tapes (DATs). PCM is also a very common format for AIFF and WAV files.
Converting to PCM will not cause you to lose any quality but you will not gain any either. If the original file was highly compressed then converting to PCM will not add the already lost information.
