unknown format??????????????????????

Hey guys. I have a NEC ND-1300A. I use RecordNow Max v.4.50
. I got the game unlimited saga and i wanted to make a backup of it. I went and bought 3 noname blank dvd-rs 4x, it said. I made the image by the book(sticky ). When i try to put the image in the blank dvd-r it gives me an error after 15 seconds. The important thing the error says is "sense:05 ASC:30 ASCQ:05"
, which in the program's help file and in the section error codes, that error means an unknown disk format!!!!!!!!!!!!Nevertheless, just before i make the recording, recordnow does see it as a blank dvd recordable (according to its legend, dark pink color) and sees that it has about 4,7 gigs free. Another crazy thing is that when i went to see if my dvd-r was at all written and thus unusable, i happily saw that it was still completely empty, however my nec drive recognised it as a blank cd-r!!!!with 648mgs of free space!!!!!!It saw that at the "my computer" . I loaded it into the cd-r drive and it can't read it so it is a dvd-r, i didn't make a mistake when buying it. But..........what the f*** is the matter here??????????????????????????????????????????
