I have just discovered this thread and, as I spent a lot of time playing with the PMD200 some years ago, I find it very interesting.
I was working with the preliminary data sheet, which was not very helpful, and the chip was very buggy. The output jitter makes re-clocking essential. The mentioned problem about having to send the setup information twice is because the output settings have to be in place before the input settings are sent. If you send the output settings first, the input syncs itself to the right output settings. Apparently, later versions of the chip do not have the option of a working hardware mode, which caused me to waste a lot of time.
I gave up on the chip when, after finally getting it working in my system, it would occasionally swap the left and right channels for no apparent reason.
