Video lengths

[llllozzajh]

Hey, i have a problem with my videos on my new latop. Is there a way to cut the last 10 minutes or so from a video as it claims to be 30 mins long but it ends after 20 mins, only to show the last 10 mins again as if that was the whole video. Thanks in advance.

There's a million combinations of yes or no to your question.

What system are you running? (Xp, Vista etc)
What type of video file?
What program are you running to view it?

etc
