I am VERY new to all this technology. I have recorded 12 short films of my son which I want to make into a DVD for my family to send abroad. They have recorded as MPEG files. Each file is about 40 minutes long & when I try to put these on to DVD using my software (SONIC) I can only fit 2 films on each DVD with only 50Mb spare space. Each MPEG I have created is around 450Mb. My question is - Is there any way to shrink or compress these MPEG files so I could maybe fit 6 on a DVD-R?
