i am using DVD-SVCD program to re-encode video for DVD-R i have done many PAL movies with no probs its so easy and result is amazing, anyway i have just done 2 NTSC movies pearl harbour and behind enermy lines, when i try to import the m2v file into Spruce up it says Invalid framerate? whats going on?

there is a tickbox which says NTSC - PAL but i left it empty as i thought it would try to change framerate or something should i tick it?

is there any way to correct the 2 i have already done so i can import into spruce as its about 15 hours of my time gone if i have to do again?

thanks in advance
