There's definatley a corruption in the file, it is quiet common for movie files to do this....
Try going into your limewire library and delete the movie from there, if you cant and limewire gives you the same error message as your shared folder did enter the file name into your computers search and when it finds it delete it from there....
Once you have done this do your system scan and check to see that it wasn't a virus...I've had this happen a few times and it was never a virus, just something faulty with the file...
