Data loss on burnt DVDs with NEC1300a

[Tim000]

Drive = NEC1300a
Problem = Disks write OK. Work OK for a week or so. Then start to lose/corrupt data!

I've burnt around 20 DVDs, various makes, +R & -R, and the write process completes without errors. The DVD will work fine on NEC and other drives for a while, and then I find the movie will stop or I cannot read the data (cyclic redundancy check error) that was originally fine.

I'm begining to think the NEC1300 drive is faulty.

Any ideas anyone?

Well, im just guessing but i think u're using cheap media and burn at 4x right? That happends do me too, thats why burn at 2X only to that kind of media and after i do a "verify written data". Not a burner issue, its a media problem.

I hope i could help ( sorry 4 my english)

what are those MAKES? also run DVDInfo on them and tell us the media IDs for these dvdrs. chances are they are subpar. thanks.

Main types used so far are Bulkpaq and Zero Defex (Ricoh). Plus a couple of unbranded disks that came with the drive.
