I have had the RH7500 for a couple of years now and has been fine using it with a digital STB. I now have bought an LG32LC2DB. I have tried every conceivable cable config but cannot get the recorder to be able to record from the DTV signals. I can use it for the analog channels but this is not acceptable. I thought being the same brand would make things easier. Not to be. Please Help, have spent hours on it with not luck.
