Nero - joining tracks - please help

Hello Folks,
I have a problem. I,m new at working with Nero and with burning. I have made a movie in Nero vision, but I cannot find out how to make the movie play all the way thru. I stops at every track. When I burn, i just get the first track. Is there a toggle, or is it somwething in the burning software.
Any help would be wonderful.
T:doh:hanks in advance

Your post is rather vague. On the main page in NV where you add files there is an icon to merge all. Highlight them, then hit ‘Merge’.
