HDD/DVD Recorder Lite-On HD-A740GX

I wonder if someone could help me with my recorder? Please take pity on a pathetic technophobe!
When trying to record onto disk, the recorder keeps telling me either I don’t have a disc in the drive or I haven’t placed the right disc in the drive. I have tried DVD+R, DVD-R and DVD RW, nothing seems to work. This is a relatively new thing as I have recorded onto disc on this machine in the past.

Is the machine faulty?
Am I doing something wrong?

What’s the best thing to do?

Best wishes,
Thanks in advance.

this seems to be a common fault with many liteon machines.
if you are not comfortable with opening the unit to replace the drive then your best bet it to get it repalced under warranty.
