I have a Sony LCD TV with 7 line inputs, line 2 is my HD camcorder input. I have been recording my home video HD movies on line 2 for the last year all of a sudden my the recorder no longer recognizes line 2, only lines 1 and 3, but I can only input the camcorder to line 2. When I input straight to the DVD recorder using only the WYR cables out from my camera it plays back on the RDR-GX300 but not on any other player or computer. I have had the recorder for 3+ years, help! Thank you.
