24fps material has a "judder" which is caused by how 24 frames per second content looks in a broadcast / delivery standard that operates in (NTSC land) a 60hz world. It's not a biggie to most . . . but some hate the look of judder (the studding you see on camera pans, etc.), and others love it. It's simply a taste issue. I find film projected (or digital projection) has plenty of judder in commercial cinemas anyway - so it's a look I've grown up on.
Frame interpolation (CFI) is a process where the projector's software is able to create "P" or predictive frames on-the-fly. These "P" frames fill in the gaps with additional (newly created data) movement between frame A and B, for an example. This featuree when turned on to its fullest can make material that originated on film (24p) or video shot at 24p look very "soap opera" like. It will give you an ultra-smooth look to all motion and action in the film. It creates the "look" of material shot at higher frame rates - such as The Hobbit (which was shot natively at 48fps). You can also use CFI for material shot at 30p to further smooth out its look.
I have this feature turned off on my Espon 5010 and my plasma TV, since I don't like it. I have played with it, and the lowest setting is okay since it barely changes the look you get without having it turned on. Using the feature is great if you like the result - but the trade-off is that you are using more image processing to achieve "a look".
Personally, I don't think it's a "gotta have" feature for most folks. If you've grown up watching movies on TV (and DVD) and haven't been bothered by how your picture looks, you likely don't need to go and pay more for a projector just to get CFI.
I'm pretty sure that the 8350 doesn't have CFI.
