Looks to me like you are an extremely naive person who believes or is
easily misled by the marketing BS that companies spew out. Canon hasn't
lied in what it has said it has just made it easy (for the ignorant
consumer who purchases equipment based on printed specs) to misinterpret
the information. As all good marketing depts do.
Canon references 1920x1080 because its imagers are that resolution. most
other camera are not that high res. My XH-A1 has 1440x1080 CCDs.
What are you so hung up about capturing at 1920x1080 when the actual
resolution of the camera is way less than that at 800+ tvl?
The camera will spit out 1920x1080 out of its HDMI port but the only
benefits will be that you can capture uncompressed or to a less heavily
compressed codec with 4:2:2 sampling rather than HDV at 4:2:0 it won't
get you any more resolution out of the camera.
