Seeing as Cablevision has decided not to carry my beloved Yankees I've decided to make the change to DirectTv. So if I'm going to make the change I figure I may as well go all out. I would like to get a receiver with either Tivo or UltimateTv capability but unsure as to which service is better. So I was wondering what are the pros and cons of each service? Which would you recommend? Thanks for any info you can give.
