My plextor makes horrible 8x audio disks it is a 8/4/32. The disks have so much trouble in portable cd players it's pathetic. Sometimes a-shock needs to be turned off so it wont get stuck half way through a song. 4x disk actually also sometimes take like over a second to change the track, but that all depends on the player and the cd-r i used. I think this old plextor does crappy audio. Disks done on my friends yamaha cd writer work just fine. sill it is. Any one else have this problem. Could cleaning possible be the problem? If so how can you clean a cd writer?
