Try to clean the laser lens using the cotton wool tip and alcohol.
In my cases this worked… additionally try different –R disk from different manufacturers. I use the TDK –R CDs and DVDs and never hand any troubles.
Thanks, I have cleaned the lense and this has han no effect. It has no trouble reading CD's bot pre-recorded and writable discs, DVD movies ans well as re- writable discs. the problem is only with write only discs?
No problem with +RW but I haven't tried +R. I have tried to burn directly from Windows Movie Maker, NTi DVD Creator, Nero, Ulead DVD Factory for Toshiba, Canon ZoomBowzer X and all work except on -R discs. I am trying to record my daughters School graduation for family so I would like to make multiple copies on writable discs so the not so techno savy family don't accidently erase re-writables. When you put the disc in the drive, it spins for a while, stops, then the drive thinks there is no disc. Any other discs, when put in the drive, spin, then the auto play window opens ready to go.
Found some interesting info in user manual. Page 78
There you can find a list of tested and good functioning disks from these manufacturers.

There is also an notification for DVD –R:
There are two types of DVD-R disks: authoring and general use discs. Don’t use the authoring disks. Only general use discs can be written to by a computer drive.
No one sells the Maxwell discs locally. I checked the discs I have been trying to write on and they are General use and the write speed is compatible with the burners speed rate. I don't know what more I can do to make sure the discs are compatible?
