Will REW work this way? ie. digital out to receiver and analog in from RS meter
Yes, but the results won't be as accurate since you won't be able to compensate for inadequacies in your soundcards frequency response because you won't be able to carry out the loopback test to create the calibration file for the soundcard. It will still work without this file, but it won't be as accurate.

wouldn't changing to analog out on the htpc in order to do the measurment distort my results, since when it actually came down to watching a movie or listening to anything, I would only be using the digital out.
You may be a bit confused here. The purpose of using REW is to create an accurate frequency response for your room and speakers, specifically to create a set of equalizer filters for a BFD to produce a smooth subwoofer response. Doesn't really matter what source you use for movies etc after the subwoofer response has been equalized. REW and your PC are only being used as a tool.
