I want to copy a file to one single-sided dvd , but the file is too large. The mpg file is 4.6 gb , which is just too large for a DVD. I dont mind losing a small bit of quality to save on buying double layered dvd's. I usually use AVSto DVD to creat my mpg files from AVI, then IMGBurn to copy to DVD. I think DVD shrink may help ? But not sure how to create the right type of file ?
