Everyone has a "favorite" brand they like to use .. but it doesn't necessarily mean it's the same manufacturer.
Lots of people say to use Verbatim or Taiyo DVDRs .. for the best burns and less wear on the laser.
If you've ever used ImgBurn .. you'll notice that the Manufacturer of the DVDs are in the info for the Disc itself. While I don't have a lot of money .. I buy Maxells from Wal-Mart. Some were manufactured by CMC or Prodisc or another I don't remember.
Do Verbatim and Taiyo DVD-Rs show up as "Verbatim" and "Taiyo-Yuden" in the Manufacturer ID?
