Had this for a few months but recently it's taken to spitting out DVD-RWs (TDK and Dr disc or whatever) if they've been in the machine when it's powered up or when I put the disc in after power up. It seems to fail to recognise the disc. However on second attempts it usually works fine. This is most annoying when using the timer record. I come home to find that the disc has been spat out at power up and nothing has been recorded Discs are formatted in VR mode. Any ideas?
