DVP3982 Not Reading DVD+/-R

I have a brand new DVP3982. Whenever I put in a burned DVD+R, I get the “No Disc” message (disc has divx files burned to it).
I have tried finalizing the disc, and tried 2 different brands.
I have burned CDRs, and it reads them just fine (divx files also burned).

It reads retail DVDs fine.

Any ideas?
