is it the mp4 that is 1.2gig or the 'raw edited' file that is 1.2gig?
also dont use 'RW' discs you dont need to, in fact some older DVD standalone players dont recognise them. just use standard discs.
if the disc is not going to be played in an older standalone player then no need to convert to 'DVD structure'. most new dvd players of say 5 years should happily play mp4.
how many of these discs are you needing to make?
have you added a 'menu' to the mp4 file and is it working on the PC or have you edited in Raw, 'dvd structure' with menu?
i'm not fully up on creating dvd's these days as i'm working the opposite way. someone with more knowledge than me might be along to help
