DVD writer does not recognize blank DVDs

Thanks for your response, sir. Well honestly, this is the first time I've ever tried to burn a DVD, and it was Memorex -R media. I haven't tried any other type. However, I did do some research into media compatibility and the info I came up with indicated that there should't be any compatibility problems using -R media. Maybe you know otherwise?

The drive is a Double Layer 8X DVD+R/RW.

yes -r is usually the most compatible, but sometimes the differences between certain manufacturers cause probs. not the brand name, but the actual factory it was made in. if u download a free program named nero infotool it will show u the manufacture code of ur dvd and u can see if that is a factory with known issues
if u already have nero burning software installed u prob already have infotool, if u cant find it in ur nero program, its easy to spot in the nero program folder, just click it and it will run
here is some info about manufacturere codes

Ok I downloaded the info tool. I put in a blank disc and the Nero tool doesn't recognize it either. There is a tab that says "ASPI not installed". What am I looking for?

Oh and I forgot to mention that I was able to burn DVDs on my other computer (Gateway Laptop / Vista) using these same blank discs (same package).

aspi isnt normally required, ignore that for now.
try this, in control panel/system/hardware/device manager see if u can tell which ide channel ur dvd drive is on, usually second ide, first position, hit the advanced tab and see  what mode it is using

it should be ultra DMA mode 2 i believe

aspi is used for scsi hi speed drives, i doubt u need it

the burner in ur other pc is prob a diff brand burner

go back and check the drives properties with infotool again, i just saw a post elsewhere that said this particular drive is only capable of +r, not -r media

i learned something there, i thought all burners would do both by this time, i thought the main prob was getting regular players to play back the diff formats

Ok I'm feeling silly now. I'm at device manager but I don't see an advanced tab anywhere.

i should have noticed in ur earlier post that it said the was +R and u used -R media

just a bit

Ok I checked the Nero tool again. Under "supported write features", there is no check next to -R media, which means this drive does not write -R media. Thanks Evining!

Hey Evining, please post again so I can accept your solution so you will get the credit.
