I'm not a MythTV user so this is a little outside my experience... but if the card is working (dmesg output indicates all is ok) and kaffeine can display a video stream from it then the problem has to be in Myth's setup.
This page on the Wiki looks like it should provide the info you need about the setup inside Myth;
