HD DVD 740 will not write

I've got an HP "DVD740" series DVD burner drive. It's one of the "Light-Scribe" ones that allow you to etch an image onto the face of special disks.

I put in any disk and it reads okay, but if I want to burn my pictures to CD-R there is no option on the left to "burn files". I have done this many times in the past and had no problem. If I right click and pick "send to" it is not on the list at all. I have tried to copy and paste also but get the error message "G:/ is not accessible. Incorrect function".

Well, I thought it might be a driver issue. I reinstalled that, but no luck.
I did burn something last night from Picasa but was wanting to save my picture files to CD and it does not work at all.

Thanks:
