The Red Green Show has posted a ton (all?) of their episodes on Youtube. Unfortunately it doesn't seem like they're super tech savvy and have literally listed all the episodes with links in a PDF file. I could of course go through the Youtube app to watch the episodes but it seems like it would add a ton of great content without a whole lot of work for the Boxee team to add it to the show library. Given that all the episodes are hosted on youtube you wouldn't have to worry about scrapers and the episodes with synopsizes are all listed in a convenient file for you.
For those of you who do not know about Red Green here is a clip, "Cadilac Backhoe":
