Problem with Liteon 32x Rewriter

[DazSAFC]

Everytime I use my Monkey branded CDRs which were excellent for my old Creative Rewriter I get Power Calibration errors and write errors for this Liteon. I`ve tryed it with a different CDR and it was fine. Is that normal, these Writers sometimes Just create coaster with a certain brand of CD's. I`ve still got about 50 of these CDRs left as well This was using Nero.
