My Praize is a great source of Christian teaching videos, so you can probably be satisfied with that. However, I would like to mention one more that you may or may not be aware of and that is the Daystar Christian Television Network. They have some great teachers on that satellite/cable channel that you can't find anywhere else to my knowledge.
