Do you think that your Plextor may have gone bad?
There is another thread, dated March 1, 2005,

that talks about a Plextor 708A going bad. I realize that this is not the same drive that you have but the 708A has DVD capabilities like your drive.
Sometimes I think that these DVD capable drives are too sensitive as compared to non-DVD CD Drives.
Just a thought,
