Taiyo Yuden cds should be excellent. You might be able to find them under the JVC brand, or listed as Taiyo Yuden at many online sites, like rima.com, meritline.com, and supermediastore.com.
For dvds, Taiyo Yuden and Verbatim are long time recommendations around here. I’d avoid the “Life Series” Verbatim discs and stick to the ones with AZO on the label. The FTI Falcon brand dvds are also said to be good.
If you want re-writable dvds, I would buy Verbatim +RW discs. And for double layer dvds, you should get Verbatim +R DL.
Since this is a media question entirely, I’m going to move your thread into our Blank Media forum.
