Several DVRs capture the raw interlaced signal allowing you to handle deinterlacing
with a quality filter in post. Same with all MiniDV cameras used as recorders
or when using a PC based capture card. A static photo won't really convey
the quality difference.
This 5.8Ghz video was captured by my flying buddy Jimmy on his Aiptek DVR. It lost a lot in
capture and YouTube recompression, but can see that the signal itself is clean and clear.
You rarely see visible noise creep into the image as it does on other band. When it
goes out it goes completely.
