People are creatures of habit. Lite-On made a name for themselves by offering CD burners that were on the cutting edge in terms of the price/features ratio.
Unfortunately, they are late-comers to the DVD burner game, and their DVD burner drives are far from the head of the pack. They feature the best CD writing speeds, true, but aren't particularly good at burning DVDs, which is why you buy them, right? Relatively mediocre compatibility with media.
The NEC 1300a drive came out a lot earlier, and is a lot more stable. It's a good all-around drive. It's a better DVD burner than Lite-On offers at this time.
