Hey! this is the very same issue i have had in the past, but I never thought of changing to a dvd+R disk, as I have always used dvd-R
I have 3 projects making up my vacation in asia.
Disk 1 with titles, fades etc... etc... and MENUS, rendered and burned perfectly.
Disk2 however, (Different footage) same everything else, FAILED. Looking at the disk, its burned only half way. I am using studio 11.1.2 and editing in HI-DEF. but burning in DVD.
I have had this issue before with studio 10, and what i do is when I create a project, i save it under a different file name every once and a while ( I may have 10 or more different files of the same project).
So now what i do is go back to a previous save, and try and burn WITHOUT the MENU. If is works, i just do the menu again and resave it.
I hope this works tonight when i get home and try it.... IF NOT! i will try a DVD+ disk and see if that will help.
thanks for the tip.....I will advise you all on the outcome.
