I've copied a few VCD *.dat to my harddisk and I want to create a DVD from them. While the *.dat files were smaller than 4.7GB, the resultant DVD exceeded 4.7GB and I was not able to fit them into the DVD. I wonder why the conversion by Nero caused it to be bigger than original even though I select the lower quality. If there anyway, I can fit them all in ? What is the best way to convert to DVD from VCD ? Thanks very much.
