Hi I have just purchased a new duo 2 with sat and cable tuners from WOS. The sat tuner works fine however the cable tuner the picture is all pixelated. I have been using a xtrend 9500 with a HMP Combo hybrid usb tuner which worked fine and now using the same coax cable in the duo2 its all pixelated. I have also tried the HMP Combo hybrid usb tuner on the VU DUO 2 with the same coax cable and that works perfectly does that mean the built in cable tuner is the issue or is there something I need to do to fix this?
