I'm not sure when the DVD will be out, but if you're ever in Canada, it's for sale on iTunes here (Along with the third season, too).
In the meantime, there are some new features on the website (www.cbc.ca/littlemosque
), including a cable TV show featuring Rayyan and Baber. I think you can only watch it in Canada from the CBC site, but some of these can be found on youTube if you search for "I on Mercy". (I'm sorry I don't know how to embed videos).
