Built amd athlon 3000 768ddr using dvd decrypter and copy to dvd program all my movies play fine except near the end of the movie it locks up and wont play anymore. this is true on multiple dvd players including computer dvd rom drive. I can use power dvd and play the vob files just fine. Copy to Dvd results show "successful" when finished copying. I formatted the HDD just before this post all to no avail. I didn't uninstall or update the firmware on the Emprex 16x dual layer burner because I have made copies successfully prior to this problem. I am using phillips dvd +R single layer media with success in the past. any kelp?
