I wanna make a copy of this dvd movie that I have. I've used dvdbackup to get a VIDEO_TS folder, then i used genisoimage to make an ISO file, and the iso plays fine when opened with VLC. However, the source is a dual-layer dvd and thus the ISO is over 8gb. is there a way to burn this onto a single-layer dvd so that i may watch it on my dvd player? And I'm using linux, btw...I don't have Windows or Macintosh.
