I have recorded a number of shows and movies using Vista media center but am having problems burning them to DVDs. When I look at the file size of a 2-3 hr movie, the file size is somewhere between 6Gb-8Gb. Since the capacity of my DVDs are only 4.7Gb, I can only assume that most movie DVDs are using some type of compression software that decompresses the file as it plays. My question is, what type of software do I need to allow me to burn these files to a DVD so I still have them without using up all of my hard drive storage space. Any help would be sooooo appreciated.
