I also realised too that the 30 days only applies if you don't start watching it after downloading to iplayer: I started to watch the "Legends" programme, but didn't have time to see it all at one sitting: now I only have 5 days left to view it, whereas, "Folk Hibernia", which I haven't yet touched, I still have 28days (both downloaded same day).
Yes, there is some good stuff on RTE: see the posting I made a couple of weeks back about Ronnie Drew. Seems to be available in the UK, but not sure re Canada!
