I just got a pioneer a06 and have been burning DV-Rs at 4x with no trouble until today when I get a queueing error every time I try to burn at 4x. I am using DVDShrink and Nero Express, on a P4 with xp pro sp1 and a gig of ram.

After failing several burns and simulated burns with spindle DV-R's by Pine as well as one by Verbatim, I was able to burn a +RW at 4x, and a regular -R at 2x. However, since I was doing so well at 4x I see no reason why it would stop working, so any ideas would be appreciated. I had easy CD creator on before but I uninstalled it, though the problems continue.
