checking to see if a video was watched?

someone used my laptop recently and downloaded a video but then deleted it so i wouldnt know. well i found the video in the recycling bin (obviously there not that smart!) on limewire. my question is..is there anyone to check to see if the video had been throughly watched, front to back...is there anyway to see exactly what activity there has been on limewire like some kind of history log or soemthing to see what key words they searched for, what videos were previously downloaded, and to see if those videos were actually watched? and help is greatly appreciated!!!
