Odd that it doesn't list the full media code, it lists AM3 for me. I've used AM3 from a few brands and it's usually decent media, none of my batches burn so mediocre as your discs, but they do vary (I usually burn at 8x, sometimes 12x). TDK as a brand has become quite disappointing with their 16x media, they use a lot of CMC M01 and AM3 and both can be decent under a good brand, but their batches are possibly the worst I've seen for those media codes. I would burn a few more in your Liteon at 8x and turn on HyperTungin and Online HyperTuning in addition to Smartburn and hopefully the burns improve as the drive learns the media (though don't expect drastic improvements). To your question on better media, Verbatim is always a good place to start, either their +R or -R would be fine. They have had some (mostly mild) consistency issues and they outsource their production to three other manufacturers, but they are almost always good to excellent discs.
