FitTV also has Namaste Yoga which is a different session each day, it plays at 7:30am here and I record them so I have copies when I can't do it at that time
It's usually easy enough for beginners yet offers challenging sessions as well, it's something always different so it doesn't get boring either! Hope this helps.
I also use the exercise TV yoga along with quite a few of their other programs... it's great!
