Can't burn more than 10 min. on a DVD??

[workinprogress]

I've been burning VCD's for two years and recently purchased a DVD burner. After reading several guides on this site and a few tries I successfully converted some of my VCD's to DVD compliant files. The problem is that I can't seem to burn more than 12 minuites on a disk. I figured this out by trial and error. If I try to put even 30 minuites on a disk it won't play. I can break up a video into 12 minuite sections in TMPGnc and then make each section a chapter in Nero and the entire video will play fine, but at each chapter I get about a 4 second pregap. I've tried to make chapters with Nero, but it won't work. My stand alone DVD player recognizes that it's a DVD, but it won't play. I don't really want to use chapters if I don't need to.
I've tried to read all I can on the subject. I have done countless trials and made lot's of coasters, I've tried different media, and I looked at the specs. of my stand alone DVD player. I can't figure out what I doing wrong.


I use the new TMPGnc Express and the Newest Nero Suite. I use Nero express to burn the video.
Please help me.

What media are you using?

DVD-R. I've tried Memorex DVD+R and Comp USA DVD-R, but no luck. They both did exactly the same thing.

run your "dvd compliant" files through mainconcept then try tmpg dvd author instead of nero

Thanks, I'll give those tools a try. If I use the TMPGEnc DVD Author, shouldn't I use the TMPGEnc encoder as well? I am very willing to try Mainconcept especially for the speed I've read so much about. I just hate to spend extra money since I've already purchased the TMPGEnc encoder.
