I am in a peculiar situation, our SD locals are off 110, but our HD locals are off 61.5. PTAT is not recording all four channels every night, sometimes it records only ABC, but more often than not it records 3 of the 4. Monday-Thursday of this week it recorded sporatically but only SD channels, Friday it recorded ABC in SD, but only the first show shows up in the guide - FFW through the recording shows all shows are there and it says the other channels were record in HD but those recordings are black and last only a few seconds before they pause. I have contacted DIRT and if we can't figure what is up, we'll get the H2000 replaced. Is anyone else having similar difficulties with PTAT recordings?
