To add a bit more, I did some poking around the forum and realized that a lot of the questions dealing with vertical stretch had pretty uninformed answers.
For example, a question Bertola asks in the forum (http://forum.gefen.com/topic.asp?TOP...rtical,stretch

I'm sure the scaler chip can accomodate this simple stretch, but I don't know if the feature is enabled.
here's pics of what I want to do: http://www.prismasonic.com/english/intro.shtml
(scroll down to: 16:9 to 2.35:1 conversion)
The answer the tech gives him is this:
" The Home Theater is currently set to expand the picture to fill all the pixels for whatever display it is connected to."
This makes me feel like either (a) the techs themselves aren't sure what Bertola was asking about (even though I feel it very well explained, especially including the descriptive primasonic link), or (b) are using an automated filter reply system or are just required by their employer to provide an answer to questions, even if unhelpful.
