My SONY DVD WRITTER AW RW-Q170A does not play any dvd.It's play some cd disk and original dvd but it can't play rewritable dvd.Please help me,sovl this problem or any idea's.

You can't. You'll have to buy a blueray disk drive.

you might want to try and update the firmware on the DVD burner, find out with the vendor if there is a fw version and how to do it, if not I would suggest hiring a professional.

It is a burner.
With DVD burners you cannot read disks, only write to them.
This cannot be fixed

On Soney.com or Drivers.com, you should be able to download the driver. You might also check to see if it needs a firmware update.

u should close the disk before u have to play it on u r home media players
try using nero any version
just uncheck the add files later option that comes just before the burn disk menu

Check that the writable DVDs you are using are compatible (+/-) with your Sony DVD-RAM.
Go to Windows Explorer and check to see if the Sony drive is visible. It may not be connected or the Jumper switch may be set incorrectly.
Check you have drivers installed, take a look in Hardware manager.
Sometimes, it's a little difficult to copy CDs and DVDs when you have more than one burning suite installed - for some reason, they 'just don't get along'. Try uninstalling any suites other than Nero.
Or it may just be that your Sony CD-RW drive is just that, and your DVD-RW drive is just that. So it wouldn't be possible to write DVDs on the CD-RW and CDs on the DVD-RW? Though I would assume Nero would detect that and use your hard-drive as temporary storage.
In Nero SmartStart, have you selected the CD or DVD tab to correspond to the project you're burning?
