CopytoDVD/CD problem

I have come across a strange problem when I use CopyToDVD.

When I burn a movie DVD and play it back in my home DVD player. The DVD spins up as if it were a CD. (DVD player is a Sampo DVE620 w/OFFA 1.4 firmware). I have not had this problem until I recently updated to version 2.2.10 of CopyToDVD. All the DVD’s I burned previously, same DVD burner and media, work fine. I’ve even burned the same DVD files with Nero and they play fine, except for the typical Nero “errors”. I’m not sure what happened in the newest version of CopyToDVD to cause this.

Any suggestions, aside from dumping CopyToDVD and using Nero exclusively?
