I recently got a new MacBook Pro, I havn't had a Mac for about 5 years, so I'm getting used to it all over again, and there might be an obvious answer to this that I've missed, but... I'm trying to get video onto iTunes, I've used 'Add to Library' and drag and drop. Either way nothing happens. The videos are all .mov and .m4v, what am I doing wrong? Secondly, I'm trying to subscribe to some video podcasts, I get the list of all the episodes, and they appear to download, but then I just get little exclamation marks when I try to play them. Any ideas?
