yeah, if you only have two hd tv;s in your house, by all means get two 722/622's. then you will still have pip and the buffer swap. but if you have more then two hd tv's, you need to incorprate the 612, or if your just watching costs then the 612 is great too. you cant really just plainly say which one is better, cause they each have their pros and cons. its going to come down to what bests suits the individuals needs. the 612 has already been a solution to a lot of customers needs. just weigh out what you need and make the choice for yourself.
