I came across this site through a post on the How to Learn Any Language forums. I thought I had found all the good sites for learning Arabic, but this one has stayed hidden from me. It's called LangMedia and they have resources for a lot of different languages, not just Arabic. As far as Arabic goes though, not only does it have a lot of MSA dialouges with translations, but there are also quite of few roleplay videos in the Jordanian, Palestinian, and Syrian dialects (also with translations). I wish I had known about this site a year ago when I was just starting with the Arabic dialects. It would have made the road a lot easier. There's really a lot to be learned from this site.
Here's an example of the kind of videos that are on their website along with the transcription and translation.
