I do not know much about this particular brand, but I do know that if I owned it and experienced the kind of early life failures you are having, I would return this product for a refund in a heartbeat.
I currently own a Pioneer Elite 620HD (my 3rd Pioneer Elite) and I fit into the category of Pioneer owner known as a "Pro Elite Bigots". I have never had a significant problem with any Pioneer product and would recommend them without hesitation.
