First, can the resulting DVD be read and played on your computer? You should be able to play the DVD with PowerDVD on your computer.
If the disc can be played on your computer with PowerDVD, but not on your DVD player connected to your TV, then the problem is most likely the brand of blank DVD disc used. Many people do not realize that most DVD blanks sold in stores are not very good. Memorex is a particularly poor brand. Try using Sony, HP, or Verbatim, and make sure to get their "premium" rather than "value" brands. The best DVD blanks are made by Taiyo-Yuden (which is now owned by TDK) and can be purchased from Meritline or Supermediastore.
