AVCHD can record both 1440x1080 and 1920x1080 formats. All depends on the camera. Panasonic released the SD1, which records at 1440x180, and then they just recently released the SD3, which captures and records to 1920x1080. So it can do both. I believe the new Canon HR10 AVCHD cam. records at 1920x1080.
