i have a HP burner, less than a year old. other discs are showing up in the computer fine, but these Tayos sometimes don't show up as writeable discs, and if i do manage to burn on one they don't verify in Nero 6. anyone else had this problem?

Could be the difference in dyes.
Cyanine dye CD-Rs were the earliest ones developed, and their formulation is patented by Taiyo Yuden. CD-Rs based on this dye are mostly green in color. The earlier models were very chemically unstable and this made cyanine based discs unsuitable for archival use; they could fade and become unreadable in a few years. Many manufacturers like Taiyo Yuden use proprietary chemical additives to make more stable cyanine discs ("metal stabilized Cyanine", "Super Cyanine"). Older cyanine dye based CD-Rs, as well as all the hybrid dyes based on cyanine, were very sensitive to UV-rays and could have become unreadable after only a few days if they were exposed to direct sunlight. Although the additives used have made cyanine more stable, it is still the most sensitive of the dyes in UV rays (showing signs of degradation within a week of direct sunlight exposure). A common mistake users make is to leave the CD-Rs with the "clear" (recording) surface upwards, in order to protect it from scratches, as this lets the sun hit the recording surface directly.

verify in Nero 6 = worthless
Too many false positives (or false negatives) in this awful "verification" method.

Your burner needs a firmware update and the firmware has to include the media code for the discs you are trying to burn. If Nero reports a failed verification, you can be sure that the disc has excessive errors. If you are able to try another burner, I believe you'll see Nero will also verify that burn.
Hewlett Packard (HP) does not make burners. They only buy others and rebrand them as their own. If you have flashed the latest firmware available from HP, you still may be several versions of the firmware behind that which is most current. I know it seems strange, but, HP's offerings for firmware often lag several versions behind that which is actually published by the company who made the drive.
Some people will flash program their HP burners to be the correct brand that they are. In other words, if your burner was actually made by LiteON, it is possible that you can flash program your HP to be recognized as a LiteON and you can then use the latest LiteON firmware available.
How to do that rebranding flash? You'll have to Google it. It's often a model specific flash procedure that must be follwed exactly using 3rd party hacked utilities to do the deed.
Or, probably the easiest would be to buy a new burner of a different brand online for about $25. Avoid Sony and HP. They are rebranded drives and they just don't often have the firmware we need. The firmware of those rebranded drives is okay, I guess, if you buy your discs at Staples, WalMart, and so forth where most everything you buy is from the same Taiwanese factories.
But, if you're using Taiyo, Taiyo DL, MAM, and other elite forms of optical media, I think your best chance for success involves buying a drive that is branded same as the manufacturer. You'll have quickest access to the latest firmware that way.
Try a Samsung, ASUS, Hitachi (LG), or LiteON drive. Be sure to Google the specific model you plan to buy in order to research its background because all of these manufacturers could outsource and rebrand once, twice, or always. It's best to look to those web sites with reviewers who disassemble the drives as part of their review and also look the web sites who have regular contributors working in the industry.
Also, if you buy a Hitachi (LG), be sure to look to the Canadian web site for firmware as it's usually a version ahead of the U.S. or other global sites.
I haven't had a NEC drive in a long time. I don't even know if they make drives any more (espeically considering that Philips plans to drop most everything except medical hardware). Maybe they still make some? NEC used to be helpful with media compatibility. If you bought media that was mostly destined for say, the European market, you could pluck your firmware from a Deutch or British site to be sure you had that media code in your chosen firmware.
Firmware file sizes are limited. Some media codes get kicked out if the drive maker thinks there's little chance that it will be needed. Sometimes they make the wrong choice and you're left with problems.
If you're using SmartBurn or whatever your brand of burning software calls it, the media code is quite important.
