Computer dont regonize dvd

hi im needing some help,did not know if this was the right forumto ask,can be moved if need to be.
i have recently burned three movies,i have ripped the with dvdfab plat,
and i burned them with nero 9
the problem i am having is they play in my standalone dvd player,but my computer does not regonize them at all. i checked them in another computer and it reconized them and ask if i wanted to play the movie.
i also check disk information in nero it says no information or disk blank,but it is not,how can i fix this so that my computer regonizes my burned dvd’s
thank you
