I stick with Taiyo Yuden media. There are some fakes out there, however, so buy from a reputable place. I bought some media on ebay (it was not advertised as any particular brand) 10 bad discs out of 50. With Taiyo Yuden, I get maybe one bad DVD or CD out of 50! I use Nero 6.6 and always check the "verify" button.
I buy all my blank media from supermediastore.com or rima.com. Outstanding quality, fast shipping, low prices, and great service (no affiliation, just a happy customer). You will find that there are various qualities of Taiyo Yuden media too... there are bulk shrinkwrapped (you don't even get a cakebox!), which are the cheapest, all the way up to the kind you can run through a special printer and print all the way from the hub to the edge. There are many in between. Wait for a sale. I bought middle-quality TY DVD-R's for less than the bulk ones. One problem: TY does not make +RW or -RW media, only -R and +R. I don't know what to suggest for +RW and -RW... I bought Verbatim made in Taiwan and have had three out of three good burns. Note that Some Sony media is made in Japan (good... probably TY) and some made in Taiwan (I cannot vouch for the quality). In general, if you can find Japanese-made media, it's going to be good. I found one cakebox of Maxell DVD-R's at Office Depot among hundreds of cakeboxes of Maxell made in Taiwan. Same with Sony. I personally have had very bad luck with Pioneer blank media (about 5% of our vacation photographs were unreadable only two weeks after I burned the discs!) and Ritek from Office Depot (the CD's have huge errors after only a few weeks... the CD's skip and eject).
