Zipped folder problems

I backed up some of my data in zipped files to put on a dvd disc.
After a while I wanted to access one and tried to extract it, but got this message

Archive: /home/tanya/Desktop/Videos.zip
[/home/tanya/Desktop/Videos.zip]
  End-of-central-directory signature not found. Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive. In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
zipinfo: cannot find zipfile directory in one of /home/tanya/Desktop/Videos.zip or
          /home/tanya/Desktop/Videos.zip.zip, and cannot find /home/tanya/Desktop/Videos.zip.ZIP, period.

Could someone please tell me what to do?

Got this output from trying another command:

tanya@tanya-laptop:/media/cdrom0$ /home/tanya/Desktop/Videos.zip
/home/tanya/Desktop/Videos.zip: line 1: PK: command not found
/home/tanya/Desktop/Videos.zip: line 2: Videos/PK: No such file or directory
