my system of dvd recorder, sky+, video is all connected as suggested via this forum. all is working except there is a strange effect when in A2 mode on the panasonic e50, with sky+ off and a ram disc inserted, - there is a horrendous feedback ( increasing sound and picture getting suddlenlyl blanched !). it only happens when the dvd-ram is incerted ans sky+ is switched off...so what is happening ???
