I'm using an 8x DRU-530A Sony DVD Burner and Philips 8x DVD+R dvds to burn my movies on. The programs im using are DVD Decrypter and CloneDVD. I have no problems encoding them with the decrypter and no problems burning them. But when i play the movie on any dvd player towards the middle of the movie and sometimes toward the end of the movie it skips every 2 seconds and jumps then stops.. Does anyone know the reason this happens? am i doing something wrong?
