I have a DVDR70 and just yesterday it refused to take R disks that are blank or part recorded, it just opens the try.
I put an recorded RW which palyed ok, don’t know if I can write yet, but will try tonight.
I will try what markbomb has sugested above, first I will try the hard reset.
I have tried varous R disks, even ones that have caused no problem in the past, in fact I recorded Battle Star last week and yesterday I was going to add to the disk, but the try just opens every time I put it in.
It plays all disks with no problem. I have to say up to yesterday I have not had any problems with this recorder I have had it for around 2 years and recorded around 120 disks over that time.
If it only records on to RW disks, I will have to put up with it, I paid around Â£300 for my unit, I can get a new phillips from super market for Â£150
