http://www.reseachchannel.org has almost nothing left for content as of midnight pacific time last night and is also gone from Dish Network. They had a crawl for a few weeks announcing that they would cease operations due to technical difficulties as of 08/31/2010 at 11:59PT and to go to the website for more details, BUT, the website only mentioned the streams and the on-demand content would become unavailable. No mention of the actual TV network being pulled from Dish or cable systems (though I would guess the part about the service being unavailable to redistributors covers that as well). The Wikipedia page mentiones them in the past tense as basically the technical difficulty seems to mean lack of funds.
