a bit vague with that question,on cable kryptview 780 has no sub and its not hd,starview 7 needs a sub to view,
move to sat and your life explodes in delight with hd,3d,it depends on what you want to do,make recordings then a twin tuner box like a vu+duo which is linux and open sourced,7 day epg needed as some boxes have only now and next showing.on any sat box to view the encrypted/locked channels a sub is needed to do more.:whistling:it depends what your fund limit is as you would need a satdish and setup also.
