I have seen nothing from either one of these except for a few brief clips in a documentary, but I'm looking forward to watching them. The first is At Last the 1948 Show, featuring John Cleese and Graham Chapman. This show actually got Cleese an offer to do his own show on the BBC that eventually became Monty Python. The other is Do Not Adjust Your Set featuring Terry Jones, Michael Palin, Eric Idle and Terry Gilliam. Do Not Adjust Your Set is a kids show, which for some reason makes me want to see it even more.
Release Date July 26th, I'm adding them to my Netflix queue today. In Canada it's a Netflix lineup.
