I bought my desktop in 2004 and it came with a Lite-On DVD+R/RW CD-R/RW burner. A few months later, I discovered that the burner could be "flashed" to an upgraded version that could do +- and DL, so after careful research I decided to do it. Everything worked fine for a couple years, but lately it has been burning discs that won't play properly in standard stereos, or it will say it burned and look like a brand new disc, or it will have an error midway through a burn. I switched brands of discs and it let up temporarily, but now it is at it again. It also had trouble with a DVD recently. Is this something wrong with my system or the drive? Would I be better off just replacing it or trying to have it repaired?
