http://www.alluc.ee/ - has the usual pop ups that are common with these sites, but it has a high number of old, new, and out of print stuff available many times.
www.tvmuse.com - similar to the above, but just tv shows. Archives don't run very deep at all, just maybe the last 3 or 4 years, aside from some major shows.
If those two fail, there is always the old "movie/show title putlockers" google search.
