i am a new owner of a mutant hd51 duel tuner , bought from wos..one cable and the other sat. i get sat channels ok . the problem with the cable tuner is i only get channel 5 but its pixelated, i have set it up for only FTAHD only. even with channel 5 i still cant watch it while recording off the sat channels. it says theirs a problem with my tuner configuration. do i loop through the tuners ?
