I have just purchased a new Panasonic DMR-E55 and I am having some trouble tuning in to the terrestrial TV channels that are received via the usual TV aerial. I get perfect pictures yet only white noise for sound. (I had no problems with my VCR and, essentially, the DVD-R has just replaced that.) I also have the unit linked to my cable set-top box via the usual array of scart cables and I have no problems. Where it does present a problem is if I want to watch something on Cable yet record a programme on, say, BBC 1. Has anybody else experienced this or, more importantly, has anybody got any ideas for possible solutions?
