Yes, they do, but remember than most HD channels use SDV, and HD Tivo is the only device that is supported ,and it's not perfect by no means. Their lack support for cable cards is the main reason I no longer have cable.
I have a vip 612 for the last 3 months ,and I have never had to reset it. Works much better than any dvr I have ever had. I love being able to record 3 programs at once. My external drive has 90 movies on it, and works flawlessly.
Why does the HD video look so poor on this channel? The rebroadcast of CBS HD games look the original via this channels. I have seen the rebroadcast of HD games on Universal HD and the look like the original. What gives with this channel?
