Here are some criteria for adding videos..
If you are adding a video about TNB, TMB, TJB, holocaust, etc . use videos on podblanc.com and wntube.net as highest priority so they dont get removed from censor happy sites like youtube.
If you are posting a full movie in the "Movies & Documentaries" or "History" category..
check on video.google.com first... Once the results come up try checking the option "Duration: Long (20+ mins)" to filter out the full videos.. then under "Any site" just select "google.com"... google's video site is better for posting full duration videos so you dont have to make multiple 'part 1 part 2' posts..
