I think this is all great but I agree, 4.7 GB for a movie is NOT HD. Its not even close. With 8.5 GB Dual Layer DVD's, 480P movies could come close to filling that. When I record MPEG2 stuff on my Windows Media Center, thats about 8 GB per hour give or take depending on what it is. Granted there could be some good compression like MPEG4 but 4.7 is way way too small to do HD. Thats like 2.5 GB per hour give or take. Not cool.
