SInce I learned of it from here, I wanted to give my review. I am trying comcast tivo out and will make deciiosn whether to conitnue to go back to series 2 or get tivo hd. have been using for a couple weeks First what I like HD (kind or irrelelvant to review) the mini screen when in menu it uses the tivo remote has a new stop button which stps recording and asks if you want to delete. to do list organization so far what i dont like the ff and rewind seem a bit off-myabe just need to get used to, seems jumpy. if a live program, doesnt ask you if wnat to add time its slow its buggy-green screen, sometimes jumps around cant advance by scenes when paused no delete folder i think everyone knows doesnt support advanced tivo functions install took hours and then i need to redo it right after he finally left. hopefully some of these things get worked out, surprised some of the basic functions dont work. i dont use much of advanced functions like potos, music, amazon, etc. i think if you are moving up from a comcast dvr, you will love it. if you are a tivo user, it may frustrate you at moment.
