I've heard that the creator of The MousePod is putting together a non-Disney podcast... expect an announcement soon.
As far as Window is concerned, I think that it's one of the more entertaining shows. My only real issue is with him (and other people) selling home-made videos of park stuff for their own profit. Creating original content is one thing - putting a camera down on Main Street, taping a parade, and then selling the resultant DVD is tacky, IMHO.
If you want to hear some excellent Disney podcasts, I'd recommend the
Disney Podcast Network. A swell bunch of people, with some very entertaining programming.
