Missing End

Hi My Problem Is When Burning Dvd Films With Nero Or Any Other Software I Keep Missing The Last 5-10 Mins Of The Film Even Though It Says Done,any Ideas

What kind of video files are you coming from?

i have converted video into mpeg.tried using different burners all the same.if i play burnt dvd on pc i can see it all but if played on dvd player dont get the end even tried it on sisters dvd and its the same.
