HVX 1080p versus DVX100B/XL2 SD uprez?

Well, you could do it yourself sort of. I posted a DV and HD shot of the same thing. You could try taking that clip of the HVX 16:9 SD 4:1:1 footage, and try up-rezzing it to see how well it'd compare against the 1080P HVX image. That would give you a general idea of how well the Canon would do; keep in mind that the DVX SD footage is lower-rez than the Canon in 16:9 mode.

I don't get it, I mean, how do you uprez an SD image? What program do you use? Are the results usually pretty good? I just don't see how a person can uprez an SD image to HD. How does this work?

Software uprez is easy just pull it into FCP set the sequence to HD insert your SD footage then stretch it fit the HD window. IF it is 16:9 you will lose the top and bottom of the image as you stretch it to make it fit. It gets pretty soft and grainy when you do this. There is a Hardware solution which should yield better results but this way will work.
Trust me. It is not even close when you look at the two images. The DV stuff's compression shows up on an HD monitor.

While I was at Sundance I attended a lecture/discussion about HD for people like us.
I was able to get a look at a bunch of footage (DV, DVCPro, HD, 16, 35) all converted (when necessary) to HDCAM SR at 1080p using a Teranex box.
While you're obviously going to see enormous benefits in many areas by shooting HD, I was absolutely stunned by the quality of the SD footage upconverted using the Teranex. Upconversion is a mathematical enterprise, obviously, and the better your algorithms, the better your result.
Doing an upconvert in FCP or any other NLE, while technically increasing your resolution, is more of a magnifying-glass-resize effect. Any compression artifacts in an SD image are going to be overwhelming when upsized in this manner.
While not perfect by any means, it is my belief after looking at the footage that shooting a feature length film on an XL2 or DVX100b and upconverting using a Teranex box is more than acceptable for feature-length indie film production.
The Teranex is prohibitively expensive to own, but the conversion cost at a post house shouldn't be. Just make sure they're using the right technology--it's the only thing I've seen that gives these results.
[The other benefit here is the conversion to 4:4:4 color space, which, while not native, does provide increased latitude for CC and chroma-keying--according to the well-informed/spoken/experienced guy leading our discussion]
