Problem to burn with nero

I try to burn some movie on dvd-r & dvd+rw but i can’t find the file on my computer, i find 1 file but when i want to open with nero he said unexpected files format, i don’t understand.
I find a another file and i try to burn with nero with all the process & when i press burn he said error speed.
Can somebody help me it’s my first movies burning.
Thanks in advance.

What exactly do you want to burn, a dvd video? A movie could be a lot for example avi or wmv etc… For a dvd-video you’ll need to find your video_ts folder, for the rest of the mentioned files you can use data dvd.

HELLO AM OT A PC GENIUS BUT CHANGE THE SEARCH TO ALL FILES THAT ALWAYS SEEMS TO FIND ALL FILMS,MUSIC ETC IF THAT IS WHAT YOU ARE TRYING TO BURN TO DVD
