I have had a E50 for about 3 months. So far twice, the lip sync has been slightly out (but noticeable) after 20 minutes on 2 RAMS. They are Panasonic RAM and recording of a Digibox via scart on RGB via AV2. The audio affects the scart and digital out of the E50. The film tonight was spawn (I could only watch a bit of it anyway) and the other was Charmed. Both were on CH5. I didn't watch any of it live. I formatted a disc afterwards and the disc didn't do it again. Is it ok to format the disc each time rather than use erase all programmes? I have heard of lip sync probs from using audio output of a digibox that hasn't been processed by the E50. I checked other RAM that I have recorded over the xmas period and they seem fine.
