It has to be said that the quality scan is about as bad as you can get & still read the DVD on the PC.

The MCC003 should be far better than that. Most (if not all) of the Verbatim media is made in Taiwan so this is not an issue. Generally Verbatim is one of the recommended brands for quality & consistency.

Burning at 2.4X does not do you any favours as burners are optimised for burning at the rated speed of the media.

Your burner apparently is not well thought of. I found numerous complaints about it, some actually on this forum.

Try burning at 8x if you can, but firstly ensure that DMA is enabled for the HD & the burner. Also regularly defrag your HD.

If once you get the TY media & you're unable to get quality scores in the 90s then you've got an issue with the burner.
