Hi, i'm new. i have a problem. i bought a DR-7621N LG DVD-Recorder and when i hook it up to my TV i hear this frequency problems likes bits or bumps on the sound. I have an Antenna on the roof. the signal is perfectly fine it shows 100% signal on my TV. i hook up the antenna to the DVD Recorder and i hear this noises. i then switch it to the TV and it sounds perfectly fine. I don't know what could be causing that the DVD Recorder only make those noises when recording from the antenna or just listening from the DVD. i once did a camcorder with the outputs recording and that came out fine. so im guessing that the DVD is picking up some kind of frequency that my TV is not. and is annoying to here those bumps and bits. any help?
