I used DVD Shrkink to compress the DVD, so it would be able to fit onto a DVD+R (I used the DVD Shrink Guide). Then, after it was compressed I used DVD Decrypter to Write the DVD to a blank DVD+R. It burned "successfully", so I tried to play it with my Power DVD player and the picture came out perfectly. However, there was no sound to the picture. Why did this occur? How can I fix it?
