What is the difference between dolby digital PCM and plain old dolby digital?

Does anyone know the difference between the two?

DD PCM = not encoded in AC3 ... could be better ... depending on number of channels, bit rate, etc. compared to the above.

It should sound better.

From memory it will wil multiple channel PCM which will be at a much higher bitrate than plain vanilla DD.
Perhaps, but not necessarily. DD could be stereo or multi ... and DD PCM could be either 2 or more channels.
In the past, I've found it common for there to be a DD (AC3 surround) track, plus a PCM (lossless stereo) track .... AFAIK due that being what would fit on the media.
Thanks for the info. I take it that the PCM will still not be in the same league as DD HD or the DTS HD?
Again, probably but not necessarily. Both are lossless, however the bit/sample rates of either could AFAIK be anything .... The HD audio formats do generally offer the higher bit/sample rates when they are available of course.
