You've configured the analog portion of the card, you should
use the DVB card settings for the HD-5500 for ATSC capture.
It is quite possible that the analog portion of the card has
the wrong default picture settings, I've yet to test the analog
portion of that card and most non-bttv frame capture card
require modified default picture settings.
