Hello I am using a Dvico FusionHDTV5 card and it works great with HDTV. Problem is when playing regular tv shows (480i ?) the video is not fullscreen on my lcd monitor. Resolution is fine with Mythtv in everything else. If I select "Fill" option regular tv shows look ok, but HDTV shows do not look ok (cant see the full picture / like pan and scan). What can I do to have 480i tv shows shown fullscreen, while keeping HDTV shows as it is now?
