Hi,
No and maybe yes. I think one episode downloaded in the wrong order, ie: I do not remember the episode numbers but, as an example, lets suppose #310 downloaded (maybe days) before #309. But now they are all ok.
Of course it takes some time for a new episode to be available in itunes after being published in youtube by Dave, but I believe that's ok.
I use itunes + iPad because, as I travel a lot, it is then that I have time to watch the episodes, plus listen to The Amp Hour. In fact I was able to catch up and watch all the episodes from #1 onwards. As Dave says, it works for me this way.
Regards, Charlie
