I have two KWorld tv tuners. The problem is whenever I try to record off one and watch tv/record off the other one, it seems like they cancel each other out and I can't watch or record off either one. TV sources are two digital antennas. I've dug around in the settings trying to fix it, but I've got nothin'. Any help on this would be great. Thanks.
