Try burning at 6x or 8x and see if works. If it doesn't, try getting Verbatim DVD+R DL 2.4x (MKM-001-00 dye) Made in Singapore blanks and it should work, or else your burner is broken.

The 'Invalid Address For Write' error is, usually, consequence of a more serious error, so please start a new thread and post the log of your burn (you can find it at Help menu -> ImgBurn Logs).
