I'm asking this question on behalf of my mum and dad, so apologies if some of rthe details are a bit sketchy. They were trying to record something last night on their DVR880. It looked like it was recording as usual. Unfortunately, when they wentr to play it back, the display said 'No Disc'. They were new discs - JVC DVD+RW discs - but on ejecting the disc and trying to play a pre-recorded one, again the display said 'No Disc'. Is this a fault which other users have encountered? Any quick fixes?
