Okay, first of all, I didn't mean that *only* the plextor premium can burn CMC media error free. In fact, I didn't even mean that only the Plextor Premium can burn HP branded 48x CMC media error free. I simply mean that the HP 48x media burned well on the Plextor Premium, and it didn't on the LiteON 48125W. If I had more of the HP 48x CD-Rs, I would have tested it on my LiteON LDW-411s for more comparison testing, but I only had 10pcs.
And yes aviationwiz, the Plextor Premium DOES burn SOME media better then other drives.... and guess what, the opposite is ALSO true. And I can easily say this as a Plextor Premium owner, as well as a LiteON owner.
For the record, My LiteON DVD burner outperformed the Plextor Premium on most of the testing on the Optimum 48x CD-Rs I tested
