So i am debating on getting the vizio co star but i am wondering if it will work with my cable? i do not have the cable box where i my tv will be set up, but i will have the cable cord (how i am watching tv now). Its an HD tv, but i dont get any hd channels, just the basic cable channels. Also, if the google tv will work, will it improve the quality of my cable tv channels to hd while watching on google tv? Thanks
