Must be old.
On the other hand if ya know its a DVD writer then -R.
-R is compatible with older dvd players and such.
On the other hand +R writes faster and has to support it.
Writers are cheap now except for blue ray. After looking myself i suspect the manufacture is LG. No, i could not find the info either. You can get a writer from Newegg for about $29.00 plus and minus. its a standard now. I burn a lot. have about 200 +R's and at least 50 -R's. maybe 50 DL dvd's.
Just for the record, i found a lot of people checking with similar problems for same model. All the comments were the same. trouble burning. there is a difference ya know besides cheap. quality of the laser detector etc. if its old then blow it out. open the tray and used static free air from maybe an office supply. you do not shake can. has an oil base. keep upright and blow it out lightly. Not full stream.
good luck.
get another.
