I am about a week into my treatment and I'm in the beginning stages of my lifelong search for the perfect mask. I tend to sleep on my stomach with one side my face mashed into a pillow, so it's not been fun so far... The mask I have used for all but one night is a Mirage LT. I am tolerating the trea...

I like the Respironics EncoreViewer, but had a couple questions:

1) What additional functionality does EncorePro offer?

2) If there are valuable features, how do I obtain a copy? It does not seem to be available to the general public...

Thanks in advance for your feedback!
