I missing something? The spec.:

*Full-HD (1920 x 1080) movies are output by the image sensor at 24p (NTSC)/25p (PAL), and recorded at 60i (NTSC)/50i (PAL). HD (1280 x 720) movies are output and recorded by the image sensor at 60p (NTSC)/50p (PAL).

So the GH1 capture 1080 progresive image and record on a interlaced stream. The big isues is if the interlaced stream it realy a PSF type of coding to a more compact progresive pakage of data. I hope that the camera it not making some sort of ĻpĻ to ĻiĻ conversion. Iīm afraid that the real MTF itīs not make more than 720 linies. Can somebody confirm that?

Regarding the band with. Gh1 always record 50/60fps at 17Mb in HQ. The 24/25fps itīs a puldown like in HVX200? If so, itīs more logicaly to record at 720p that to record at 1080 with less bandwith per frame?

Why the only whay to record native fps itīs in MJPEG at 720p 30fps ?
