If someone discusses a specific torrent that is found to have copyright protected material in it, then that discussion will be shut down. Not all torrents are sharing material that is copyright protected however, and any threads about those are certainly allowed, as are any comments about the bittorrent protocol itself.
You should read our guidelines for discussions regarding copyright protected material: http://club.myce.com/f34/guidelines-copyright-protected-material-316049/
Since you wish to download a rented video, against the terms of your agreement with Vimeo, you are asking for help that we cannot provide according to our rules. Therefore, I am closing this thread.
