Hi to everyone...this is my first post on this great site! OK, straight down to business. I have a Lite-On DVDRW SOHW-1213S drive. I've had this drive for approx 4 months. I have never had a problem reading or writing with this burner, UNTIL recently. A few weeks ago I tried to play a retail DVD in my PC, but it wouldn't play. Strange I thought, but I put it down to the DVD, not my drive. I don't think prior to last week I had ever burnt a "dud" DVD or CD with this drive...no problems whatsoever. BUT, that all changed last week. In the space of 24 hours I burnt 15 coasters. I was shocked. 5 were my normal imation dvd's, 5 were TDK and 5 were TEAC. So yes, I tried different brands. The drive spins REALLY fast, so I don't know if that has anything to do with it. I actually got one of the 15 to work, but the burn I have done, a backup of a heap of stuff, now can't be read. I thought maybe it was my PC, so I gave the drive to my brother for him to try in his PC. It worked fine. He found it spun really fast too, and took a while to read data, but besides that it seemed fine. I've got the drive back from him today,tried to burn a DVD, and IT DOESN'T WORK! I tried playing a retail DVD in it...DOESN'T WORK. Burning CD's isn't a problem, which to me is strange, but I'm a newbie with all this. I thought i'd load a dvd into DVD Shrink, and I get the following error: Can someone PLEASE point me in the right direction with this. Are their programs out there that actually test the correct functionality of a DVD drive? Is my drive stuffed? Is it something to do with my PC? My MOBO? As I said above, i've never had burning problems before, it's like happened overnight and i'm stumped! Thanks!
