Help - can't burn DL DVD+R discs

Question

I just purchased a spindle of Memorex Dual Layer DVD+R discs to backup some of my project folders that are too large for single layer DVDs.However, I am getting the following error message at the start of every time I try to burn a disc.
"The disc can’t be burned because because communication between the computer and the disc drive failed (error code 0x80020022)."
I've been reading that others are also having a problem with burning DL-DVDs. Is this a drive problem or a media problem?
After the first 2 tries, I checked the "About this Mac" and saw that under "Disc Burning" it said I have a MATSHITA DVD-R UJ-868 drive and that for both CD write and DVD write it says -R -RW. Does that mean it doesn't support +R discs or DL discs.
I went back to the tech spec page for the MacBook Pro that I have (I bought it 3-1/2 months ago, so it's still new and should have the same specs listed, and there it states the specs as "Maximum write: 8x DVD-R, DVD+R; 4x DVD-R DL (double layer), DVD+R DL (double layer), DVD-RW, DVD+RW; 24x CD-R; 10x CD-RW"
So what is the issue here, and is there a fix for this?

Hi eric,
Your drive, as the specs say, should be able to burn +R discs.
As Bram has suggested , when only -R discs appear under system profiler this can usually be rectified by simply resetting the PRAM, and sometimes simply by restarting normally, though on rare occasions some level of OS re-installation can also be required.
Those Memorex discs are a bit of a worry , too, though. Generally you are better off sticking with Verbatim, Maxell or TDK with Apple drives. Memorex have a somewhat unfortunate reputation for compatibility problems, I'm afraid, though it depends which actual third party manufacturer has supplied them with your particular batch to some extent.
But you will need to sort out the "-R only" problem first regardless. Once you have done this you may find that your particular batch of Memorex are fine. I'd be very wary about buying them for your Mac in future , though.
Cheers
