You have about 20% more detail in the 1080 picture, but 100% more pixels to record it in. So a lot more bandwidth allocated per pixel.
It’s true that in both 1080 and 720, a 6.7:1 compression ratio is used. But the thing is, in 1080 mode, there’s twice as much bandwidth per frame, but not twice as much detail. So the 1080 mode places a lot less stress on the codec than the 720 mode does. This results in milder compression artifacts etc; it effectively gives you around 80% more bandwidth.

I would shoot 1080/24p for any keying situation. You get a tad more detail, but you get effectively quite lower compression, which gives you a cleaner image to start from.

Not that I know of, but P2 Genie can auto-increment reels as it offloads.

Doesn’t work, there is no component output when playing a firewire-input signal.

The problem is the PAL vs. NTSC units; the FireStore is sold specifically in a PAL-compatible version and an NTSC-compatible version, you have to use the right one with your camera.
As for the firewire stream: on the US/NTSC version the firewire stream is always 60p (for 720) or 60i (for 1080/480). On the PAL version the firewire stream is always 50p (for 720) or 50i (for 1080/576). Any other frame rate gets embedded within the 50p or 50i data stream, so 720/25p is transported through firewire as 720/50p with each frame being rendered twice.

No such thing. Tapes aren’t PAL or NTSC, they’re just data tapes. If you recorded it on a US/NTSC DVX, then the footage on the tape was recorded in the NTSC format, and won’t play in a PAL-format camera.

All DV-based formats (DV, DVCPRO, DVCAM, and DVCPRO50) are 720×480.
