[Matt Devino] “looks about 3 stops more sensitive”
THREE STOPS? Forgive me for doing a spit-take here, but — three stops? I just spent a couple of days with both of these cameras side by side, and I did have a waveform monitor and a vectorscope and my DSC charts, etc., and sensitivity is one test that I ran. When both cameras were configured to deliver a fundamentally identical image (i.e., comparable gamma, comparable color rendition, both in 1080/24p mode, both in 180-degree shutter) the EX1 was more sensitive — by 1/2 of one stop. 0.5 stops. Not three stops! One half of one stop.
Granted it is more sensitive, but not by the Paul Bunyan-sized tales that are being spread about it. It is much cleaner in noise though. If you push the EX1 to 6dB, it’s about as noisy as the HVX is, so if you want a noise-to-noise sensitivity comparison I could see claiming 1.5 stops. But three stops is just… not realistic.

[Noah Kadner] “One issue is that the CCD chips are supposedly somewhat more optimized for 720p.”
I don’t know what this means. The system delivers more resolution in 1080 mode than it does in 720 mode, so how would the CCDs be more optimized for 720?
Granted, 1080 mode doesn’t deliver a huge res boost over 720 mode, but — hey, if you want what the system can deliver, why not get all that it can deliver? 1080 is higher res and less compressed than 720, on an HVX200.

I’ll practically guarantee you that your footage was fine on the cards, and something went haywire when FCP imported/converted it.
I tell everyone with FCP: Use Raylight. It avoids any and all hassles. Raylight isn’t just for PC, Raylight for the Mac lets you directly edit your footage without using any sort of conversion to Quicktime. You edit off the camera-original MXF files, so you won’t have any issues at all with clips failing to import, or frame rates changing on you, or audio distorting, etc.
-
FCP’s import window is the least reliable way to get footage into FCP. Use P2 Log Pro or Raylight and all your clips will come in every time.

Shoot at 2fps with 350.0d shutter. Use the “Frame Rate Hack” to get to 2fps.

Did you run the “organize p2” step on the FireStore before trying to import the footage? By default the FS-100 doesn’t make P2-compatible files; you HAVE to run that “organize P2” command on the FS-100 before you try to import.
-
For clarification, while what Shane says (P2HD = DVCPRO-HD) was basically true at the beginning, it’s now more than that. P2HD includes DVCPRO-HD, but it also includes the new AVC-Intra format too. And may someday include other formats if Panasonic chooses to develop more formats.
So it’s not necessarily a case of P2HD = DVCPRO-HD, it’s more a case of P2HD *includes* DVCPRO-HD (plus a lot more, such as AVC-Intra, DVCPRO50, DVCPRO25, and DV).

[jodyberry] “It almost looks like it would take an existing camcorder battery.”
It does. It uses the same battery and charger as the DVX100 and HVX200.

So does the Infinity. Every rolling-shutter CMOS camera has the “rolling shutter” issues. If you want to look at a rolling shutter camera, you’d better know what the rolling shutter does and how it affects your footage.

The P2 system is designed to protect you from losing footage. It “closes” the file system every two seconds (during normal recording; not sure how it works for interval recording); that means that in a normal circumstance the most you’ll ever lose would be the last two seconds.
Try the “repair clip” function, as Jan said. I bet it’ll work and your footage will be just fine.
