Here you go guys, Have a chew on this! I have got 25 mpgs all of a series, I want to copy these to DVD, each mpg is approx 500mb but when I drop them into neoDVD the projected image is around 2.5Gb, how can I get them, so that I can have 3 or 4 episodes per DVD. do I need to compress them down in any way. the mpgs are in a VCD format (screen size, audio @44100 etc.) I know that DVD works on higher resolutions and higher audio bitrate, but should the image be that big?

Cheers

Jeff
