I have been having an issue with my optical drive (PLS DVD+-RW DH-16A6S) in regards to writing and reading. When burning video files to a DVD-R or DVD+R I sometimes encounter problems when playing the completed disc. Files will not open, will skip, or will freeze and the folder displaying the disc contents sometimes locks up (Not Responding). My most recent issue is with MP3 discs. When playing MP3 discs, I will encounter skips. Sometimes at the end of a disc, and sometimes at the beginning or middle. Erasing a glitchy CD-RW MP3 disc and then reburning the project again on the same disc will not skip in the same place. It may instead skip elsewhere or be perfectly fine. I experience these issues when burning with both Roxio and BurnAware Free. I have cleaned the laser with a cleaning disc and done my best to keeps everything dust free. Does this indicate my drive is starting to go?
